Summary

Magos and Joseph are a married couple devastated by the death of their 11-year-old son, Santiago, a boy born with only one lung who managed to live much longer than doctors had predicted. 

His death at their remote home in Firgesan, Upstate New York, shatters their lives. In a feverish act of grief and denial, Magos secretly cuts a piece of Santiago’s lung and preserves it. 

This desperate act begins her descent into a new, surreal phase of mourning.

Believing the lung holds a part of Santiago’s spirit, Magos begins to feed it chicken broth, nurturing it like a mother would a newborn. Against all odds—and logic—the lung grows into a living entity. First a grotesque blob with a mouth and a tail-like appendage, the creature horrifies Magos’s old friend Lena when she visits. 

Despite its monstrosity, Magos loves the creature fiercely, interpreting its existence as proof that Santiago can somehow be saved or reborn.

Magos smuggles the growing creature back to her childhood home in Mexico City, hiding it from the outside world. 

As time passes, the creature, whom Magos names Monstrilio, gradually develops humanoid features—arms, legs, speech—but retains monstrous traits like fangs, a thirst for raw meat, and a prehensile tail. 

Monstrilio’s existence strains Magos’s relationship with everyone, including Joseph, who has remained more grounded in reality but is unable to completely resist the dream that their son might return.

As Monstrilio continues to mature, the family faces a troubling choice. Joseph believes that to help Monstrilio live a normal life, they must remove his more grotesque features—especially the monstrous tail. After much painful debate, Monstrilio undergoes surgery. 

The loss of his tail, however, also severs part of his vital, primal spirit. No longer fully monster nor fully human, Monstrilio begins to physically and emotionally deteriorate.

Magos and Joseph try to integrate Monstrilio into society, treating him more like a traditional son, but he struggles to conform. 

He feels isolated, confused, and increasingly detached from his adoptive parents’ hopes. 

His alien nature asserts itself in dark and unpredictable ways. Friends like Lena, who once supported Magos, start to distance themselves, recognizing the dangerous folly in trying to force Monstrilio into human norms.

As Monstrilio grows sicker and sadder, it becomes clear that love alone cannot sustain him. In a heartbreaking turn, Joseph decides to end Monstrilio’s suffering, framing it as an act of mercy. 

Magos desperately tries to intervene but is ultimately powerless to stop Joseph. Monstrilio dies in a second, final death—this time irrevocably.

The aftermath leaves Magos adrift once more, forced to confront the magnitude of her grief and the moral ambiguity of her actions. 

She must reckon with difficult questions: Was Monstrilio truly her son reborn, or was he something entirely new—a creation of her sorrow? 

Was her love for him pure, or selfish?

As the novel ends, Magos begins the long, uncertain journey toward acceptance. Life cannot be undone or recreated through magic or grief, no matter how deep the longing. The novel closes on a quiet, devastating note, leaving the reader with a deep sense of the monstrous beauty of human love and loss.

Characters

Magos

Magos, the central figure of Monstrilio, is a mother consumed by grief. After the death of her son, Santiago, she is unable to let go of the pain and resorts to an extreme act of bringing him back in some form.

The character of Magos reveals how grief can become all-encompassing, blurring the lines between love and madness. Her decision to create Monstrilio by cultivating Santiago’s lung represents both her desperate yearning to maintain a connection to her lost child and her ability to create something monstrous out of love.

Magos is portrayed as fiercely protective of Monstrilio, seeing in him not just a creature, but a continuation of her son, Santiago. Her role as both creator and mother underscores the conflict between affection and horror that she feels toward the being she has shaped.

Despite her initial devotion, Magos is ultimately confronted with the realization that her grief has created a being that cannot be easily understood or nurtured, forcing her to face the painful truth of what Monstrilio represents.

Joseph

Joseph, the father of Santiago and husband to Magos, is deeply affected by the death of his son but in a more pragmatic, yet equally devastating, way. While Magos is overwhelmed by grief and emotional chaos, Joseph channels his sorrow into more practical decisions, such as advocating for Monstrilio’s surgery.

His character embodies the tension between reason and raw emotion, with his attempt to “fix” Monstrilio through surgery symbolizing his desire to restore normalcy. However, Joseph’s decision to kill Monstrilio in what he believes is an act of mercy highlights his inability to fully cope with the loss and his growing sense of helplessness.

His actions demonstrate a deep internal conflict—while he seeks to protect Magos, he is also driven by the need to confront the monstrosity that Monstrilio represents. Joseph’s love for both Santiago and Monstrilio is complicated by his inability to navigate the space between mourning and letting go, ultimately resulting in the tragic end of the creature he once hoped to save.

Lena

Lena, Magos’s best friend and a surgeon, represents the rational, scientific perspective in contrast to Magos’s emotional tumult. Initially supportive of Magos’s desire to create Monstrilio, Lena becomes increasingly uneasy as the creature grows and the moral and ethical implications of its existence unfold.

Lena’s character is crucial in portraying the tension between reason and emotional attachment. As a rationalist, Lena is the first to question the ethics of nurturing a creature that is both human and monstrous.

Her shift from support to detachment reflects the growing discomfort of the external world with the family’s situation. She is also a critical voice in Magos’s life, pushing her to confront the darker consequences of her actions, yet her own emotional detachment reveals a gap in her understanding of the deep bond between mother and creation.

Ultimately, Lena’s relationship with Magos deteriorates as she becomes more critical of their choices, representing the growing isolation of Magos and her creation.

Monstrilio

Monstrilio, the creature born from Santiago’s lung, is both a symbol of hope and a tragic reflection of grief. In his monstrous form, he embodies the unrelenting pain of loss but also the impossible desire to resurrect the past.

Initially an amorphous blob, Monstrilio grows into a creature that is part human and part monster. His development throughout the novel mirrors the deterioration of Magos’s psychological state, as she continues to treat him as a surrogate for Santiago.

Monstrilio is trapped in an existential struggle, neither fully human nor entirely monster, a reflection of the confusion and turmoil that arises when grief is not properly processed. His rebellion against the societal and familial expectations placed upon him highlights his deep sense of alienation.

Monstrilio’s eventual decline, both physically and emotionally, and his tragic end serve as a powerful commentary on the consequences of trying to control or recreate life. His death underscores the novel’s exploration of the limits of love and the necessity of letting go, even in the face of overwhelming grief.

Jackie

Jackie, the childhood housekeeper of Magos, serves as a more superstitious and practical foil to the rational characters in the story. She is wary of the creature Magos has created, sensing that it is unnatural and perhaps dangerous.

Jackie represents the voice of folk wisdom and caution, contrasting with the more modern, scientific approach of Lena and the emotional, grieving stance of Magos. While she is not a central figure in the narrative, Jackie’s warnings about the creature and her belief in the supernatural add a layer of tension and foreshadowing to the story, highlighting the danger inherent in tampering with life and death.

Her role, though minor, underscores the theme of resistance to the unnatural act of creating life from grief.

Santiago

Although Santiago is physically absent for most of the novel, his presence is felt through the character of Monstrilio. Santiago’s death and the grief it causes Magos form the foundation for the entire plot.

The child, who was born with one lung and given little hope to survive, lives longer than expected, and his death is a traumatic event for his parents. Santiago’s love of dinosaurs and monsters becomes a motif that reappears in Monstrilio’s own monstrous form.

Santiago’s essence, though not literally present, is transferred into Monstrilio, representing the intersection of memory, grief, and the desire to preserve lost loved ones. His character, though not active, serves as the catalyst for the novel’s exploration of love, loss, and the consequences of resurrecting the past.

Themes

The Destructive Nature of Grief and the Creation of the Monstrous

One of the central themes of Monstrilio is the destructive and all-consuming nature of grief. The protagonist, Magos, deals with the profound loss of her son, Santiago, who has lived far longer than expected despite being born with only one lung.

This immense grief leads her down a path of obsession and madness, culminating in her creating a grotesque creature from a piece of Santiago’s lung. Magos’s grief does not simply manifest in sorrow; it transforms into an active attempt to defy death, to resurrect what has been lost.

In this process, grief itself becomes monstrous, as Magos’s attempt to recreate Santiago blurs the line between love, madness, and the creation of something unnatural. The creature, Monstrilio, is both an expression of her love and an abomination born from her refusal to accept the finality of death.

This theme highlights how grief can warp the mind, leading individuals to make decisions that transcend moral boundaries in an effort to reverse or deny the inevitability of loss.

Identity, the Body, and the Struggle Between Humanity and Monstrosity

Another significant theme is the exploration of identity and the tension between humanity and monstrosity. Monstrilio is not just a creature; he is a being who occupies the uncomfortable liminal space between human and monster.

As he grows, he begins to adopt more human characteristics, but his monstrous traits—fangs, a tail, and a predatory nature—persist. This tension between his human-like form and his monstrous instincts underscores a deeper exploration of identity.

Magos and Joseph’s attempts to raise Monstrilio as a “normal” child, including the controversial decision to surgically remove his tail, reflect society’s attempts to force conformity and suppress what is perceived as unnatural. The novel raises questions about what makes someone truly human. Is it their appearance, their actions, or something more intrinsic, such as their capacity for love, compassion, or the ability to connect with others?

Monstrilio’s struggle with his identity exemplifies how individuals may wrestle with their own sense of self when they are caught between conflicting aspects of their being, whether that be the monstrous or the human.

The Ethics of Creation, Control, and the Limits of Parental Love

The theme of creation and control also plays a crucial role in Monstrilio, particularly through the lens of parental love. Magos’s act of creating Monstrilio is an attempt to hold on to her son, Santiago, beyond death.

However, as she nurtures and raises Monstrilio, the question arises: is her love truly for the creature that he has become, or is it a desperate attempt to hold onto something she cannot bear to lose? 

This brings into question the ethics of creation—what right does a parent have to shape a life in their image, especially when the life in question might not even be human?

Magos’s creation of Monstrilio can be seen as both an act of love and a violation, as she molds the creature to fit her emotional needs, rather than respecting its autonomy. This theme also extends to Joseph, whose desire to “fix” Monstrilio through surgery reveals a more pragmatic, but equally controlling, approach to parenting.

Both Magos and Joseph’s actions, driven by grief, reveal the potential dangers of trying to control the life of another, especially when that life is tied to personal loss.

The Intersection of Magical Realism and Horror in the Depiction of Loss

Monstrilio employs elements of magical realism and horror to explore profound human emotions. The creation of a living being from a piece of tissue is fantastical, yet the emotional reality of grief, loss, and the desire for resurrection is grounded in a deeply human experience.

This blending of genres serves to heighten the emotional impact of the story, using the surreal to emphasize the psychological and emotional horror of the situation. The creature, Monstrilio, is both a product of Magos’s magical thinking and a monstrous result of her grief-fueled actions.

As the creature grows and becomes more dangerous, the narrative weaves horror into the fabric of human experience, suggesting that the true horror lies not in the monstrous form of Monstrilio, but in the emotional and moral decay caused by unresolved grief and the inability to let go.

This intersection between magical realism and horror challenges the reader to confront uncomfortable truths about the human condition—how love, loss, and the need to control can shape the most terrifying and tragic outcomes.

The Ethical Dilemmas of Mercy, Death, and the Consequences of Choices

A crucial turning point in the novel is when Joseph decides to end Monstrilio’s life, believing it to be an act of mercy. This decision raises profound ethical dilemmas about death, mercy, and the consequences of parental decisions.

Joseph’s choice is portrayed as an attempt to release Monstrilio from suffering, but it also exposes the darker side of love—the capacity for a parent to end a life they helped create. This decision brings forth the moral complexity of the situation: Was it truly merciful to kill Monstrilio, or was it an act of selfishness, driven by Joseph’s inability to cope with the creature’s existence?

The finality of Monstrilio’s death and the aftermath of this decision force both Magos and the reader to grapple with the consequences of trying to impose one’s will on life and death. 

The novel ultimately poses a difficult question: When is it right to let go, and when does love require that we hold on, even when it leads to destruction?

The Inescapable Nature of Grief and the Futility of Recreating the Past

Finally, the theme of the inescapability of grief and the futility of attempting to recreate the past permeates the novel. After Monstrilio’s death, Magos must confront the reality that she can never bring Santiago back, nor can she ever truly recreate him.

Monstrilio, as much as he was a reflection of Santiago’s essence, is not the same person. In her attempt to resurrect Santiago, Magos inadvertently creates something that cannot fulfill her emotional needs.

This theme is deeply tied to the idea that grief is not something that can be fixed or reversed; it is a process that one must learn to live with. The novel concludes with Magos grappling with the loss of both Santiago and Monstrilio, underscoring the impossibility of reclaiming the past and the necessity of moving forward, even when the emotional weight of loss is unbearable.

This theme speaks to the universal human experience of mourning, reminding us that while love and loss shape us, they are not forces that can be controlled or undone.
