Quick Facts

Short Summary

In the opening chapter of Monstrilio, Magos and Joseph lie beside their dead son Santiago in his child-sized bed in their secluded Upstate New York house. Magos reflects that his death lacks the drama she once imagined — she had fantasized about him dying in a Mexico City mall where she would be an object of public sorrow. Joseph grieves physically, whimpering and nuzzling the boy, and Magos eventually folds his body and walks him to their bed. Alone with Santiago, she licks his ear like an animal, notes his worn dinosaur pajamas, and decides that his single lung is the core of his identity. Determined to possess it, she makes an incision in his abdomen, finds the lung, and slices off its tip, placing the piece in a jam jar. She reassembles his body and cleans the bed. When Joseph returns, he freezes at the scene and tells her she has destroyed their son.

Full Summary

The novel opens in a bright room in a secluded house in Upstate New York, where Magos and Joseph lie on either side of their dead son Santiago in his child-sized bed. The boy's body is silent and unbreathing; there is no thunder, no weeping angels, no cloaked Death — just the blunt fact of his stillness. Magos reflects that she cannot rally the drama she once imagined. In her fantasies, her son died in a shopping mall in Mexico City, where an audience would surround her in hushed awe and she would become a Pietà, marble and gorgeous, crying fat, clean tears. Now, with only her whimpering husband as witness, she feels nothing — not a tear.

Joseph grieves physically. He nuzzles the boy's neck, squeezes him with his whole body, grunts, and breathes loudly against the child's skin, as if he knows how to grieve and she doesn't. He grabs her arm and pulls her toward the middle of the bed, as if together they might bear the boy again. Magos thinks, I bore him. I won't bear him again. She sweeps Joseph's blond hair off Santiago's face even though she knows it can no longer tickle him. Joseph goes slack, and Magos, too tired to check whether he has died too, leaves the bed to open a window. The spring air is fresh and very undeath-like.

She thinks about the events that follow a death — cremation, a funeral, black clothes, sad family and friends — but she is not done with her son, not yet ready to hand him away. In the mornings, an owl hoots outside, thinking itself a rooster; Santiago loved this owl, his tiny body wound in rapture. She listens for it but may have missed it.

Magos folds her husband: prying his fingers from their son's pajamas, folding his fisted hands into his chest, pulling his legs off the bed. She holds his thick thighs longer than she needs to — they are a comfort to her. She swivels his head away from the boy, and Joseph shuts his eyes, squeezing out tears. She holds his head to her chest so he can muffle his sobs, and walks him to their bed, where he curls defeated. Their son is only hers now.

Alone with Santiago, she lies next to him and licks his ear, like an animal would. He remains dead. She studies his cream-colored pajamas illustrated with silly dinosaurs in bright colors; they show thinning patches where the soft material has wearied. He would have worn them exclusively, roaring his way through the day, if she hadn't forced him to wash and change.

She wants to learn one last secret from her son: what part of a person's body is inextricably themselves? Not hair — too public, not a secret. Not his fingers or toes, which she knows well. Not his tongue, quick and lispy. Not his heart, a quiet, solitary heart engaged to her and her husband. It has to be his lung. Santiago has only one lung, and this lung is the core of his Santiagoness — a mystery to her, a tiny lung that carried her son past his expected life span. She loves and hates it, wants to thank it and spit on it for not carrying him further. Mainly, she wants to see it and hold it.

Excavating one's child isn't difficult, if determined. She breaks skin with a sharp knife — her husband keeps their knives sharp, essential for a good cook. She performs the first incision on her son's belly with utmost care, lest Santiago wake up in a sudden rebirth. He doesn't. Her next cuts become bolder. She sneaks her hand under his ribs — she will not break them — to find the lung. The procedure is messy; his heart no longer pumps, so what oozes out is the blood his veins already carried.

She remembers a Lorca play produced at the UNAM, in which a mother kneels and delivers a monologue about what it means to see her son's blood spilled on the ground. The actress mimicked soaking her hands in blood and licking them, because the blood is mine. There isn't enough blood for Magos to soak her hands, but she smears and licks them anyway, savoring the taste of iron and warmth. She could suck more blood from his veins but won't — she's not a vampire, though now she understands the impulse, the craving to drink deep and thirsty in her bowels.

She finds the lung toward the right of his chest — lighter and more inconsequential than she thought it would be. She wants to rip it out and keep it for herself, but she pulls gently, still thinking she can hurt her son. It won't detach. The bed is a mess. She whispers his name like an apology. Though she made this lung the same way she made the rest of him, she decides her son should keep his lung. She'll only take a nugget. With a paring knife, she slices a piece — the downmost tip. This chunk is hers.

She places the chunk of lung in a clear jam jar her son used to keep pencils in. There's no lid, but she knows where to find one. She wraps her long hair in a bun, fastens it with a pencil, and, as best she can, puts her son back together — unfolding the skin of his open belly, soaking a piece of sheet in her saliva, and wiping dry blood off his body.

Her husband comes in and freezes, trying to make sense of what he has walked into. She had planned to change the sheets and wrap Santiago in a clean set to spare Joseph the sight of their son's maimed torso. She doesn't know whether he will scream, hate her, or understand her. You've destroyed him, he says. She finds the word destroyed curious. Has she really? No. She has destroyed nothing; nothing was left to destroy. But she has made a mess. Magos, he says, as if her name could summon an explanation. Joseph, she returns, letting him know she sees him standing there, gaunt and pale green.

Main Characters

Magos

The grieving mother. Driven by a desire to possess the lung that defined her son, she makes an incision in Santiago's body and preserves a piece of it in a jam jar. She is emotionally numb at first — she cannot cry — and reflects on her fantasy of a dramatic public death. She is practical and determined, folding her husband's body and walking him to bed before performing the excavation alone. She licks her son's ear like an animal and savors his blood, understanding the vampire's impulse.

Joseph

The grieving father. He grieves physically — whimpering, nuzzling, squeezing the boy with his whole body, breathing loudly against his neck. He seems to know how to grieve, while Magos feels she doesn't. He goes slack and is folded by Magos and walked to their bed. When he discovers what Magos has done, he freezes and tells her she has destroyed their son.

Santiago

The deceased son. He lies in his child-sized bed wearing cream-colored dinosaur pajamas with thinning patches. He has only one lung, which carried him past his expected life span. He loved the morning owl. His body becomes the object of his mother's desperate act of preservation.

Themes

Grief as Bodily Instinct

Grief in this novel is a physical compulsion rather than an emotional process. Joseph nuzzles, squeezes, and breathes into his son's body; Magos licks his ear and savors his blood. Mourning is something the body performs before the mind can process it.

Imagined versus Real Death

The novel contrasts a fantasy of dramatic, publicly witnessed death with the private, unglamorous reality of loss. Magos imagined her son dying in a Mexico City mall where she would be a Pietà; instead, he dies quietly in a child-sized bed, and she cannot rally a single tear.

The Solitude of Parental Grief

Divergent responses to a child's death reveal that grief cannot be shared, even between parents who loved the same child. Joseph grieves physically and openly; Magos is numb and calculating. Their mourning is fundamentally solitary.

Ownership of the Dead

The novel raises questions about who has the right to alter or possess the body of the dead. Magos's incision into Santiago's body frames remains as contested territory between mourners — Joseph's horror at her act underscores the conflict.

Preservation as Defiance

The act of preserving a fragment of the dead transforms preservation from sentiment into resistance against the finality of death. Magos's jam jar becomes a vessel of defiance.

Symbols

The Lung

A concrete bodily organ that the mother excises from her son's corpse, treating it as the singular essence of his identity — the core of his Santiagoness — and the seed for the monster that follows.

The Owl

A concrete animal explicitly linked to the dead son. Santiago loved the morning owl that hoots outside the house, and Magos listens for it after his death, making it a recurring emblem of his presence and the family's grief.

The Act of Preservation

A motif centered on the mother's incision into the body and her storing of the lung in a jam jar, reflecting a desperate attempt to keep the child's essence from disappearing.

The Act of Consumption

A motif that appears through the mother's licking of her son's ear and her savoring of his blood, tying mourning to a visceral, bodily hunger.

Ending Overview

The chapter ends with Joseph discovering Magos's act and telling her she has destroyed their son. Magos reflects that she has destroyed nothing — nothing was left to destroy — but she has made a mess. The chapter establishes the central conflict: the divergent ways the parents grieve and the act of preservation that will set the rest of the novel in motion.
