Monstrilio by Gerardo Sámano Córdova

Monstrilio by Gerardo Sámano Córdova is a book that has stuck with me. If you are a reader you likely know what I refer to – a book that lingers after you’re finished reading, one that leaves a mark. Monstrilio is that for me. In a past book review I mentioned that I have been exploring horror fiction, a genre that until recently, I didn’t really pick up. I’ve read a handful so far this year, Monstrilio being the most recent, and I am becoming more and more content with my new reading exploration. A debut novel, Monstrilio is a horror novel with literary leanings released in 2023 by Mexico City author Córdova. I think there are a lot of ways to describe this unique novel, it runs the gamut of emotions, but in essence this novel explores extreme sorrow and immense love through the story of a boy that becomes a monster that becomes a man.

The novel is told in four parts by four different main characters. It opens with Magos on the most devastating day for a parent: she and her husband, Joseph, lose their 11 year old son, Santiago, who dies from complications of living with one lung. In her grief, Magos opens the body of her son and removes a chunk of his lung. “One believes the stupidest things in grief,” Córdova writes, and this is one of those things. Magos believes if she cares for and feeds the piece of Santiago’s lung he will come back to her.

Much to her family’s surprise (and horror), it works…in a way. From the piece of lung grows a black furred, ferociously hungry being, or monster, if you’d like. However, he is not Santiago, although he carries some likeness in addition to the lung. Magos calls him Santiago, while Joseph and Lena (a good friend to Magos and Joseph) call him Monstrilio. 

What follows are short segments moving forward in time as Monstrilio matures, learning to adapt to his circumstance and live like a human. Following Magos’ narration is Lena’s, the friend and doctor in love with Magos who often helps care for Monstrilio’s not-so-human health. Then, Joseph takes over narration. Monstrilio is now a young adult living with Magos and going by his new name, M. Joseph and Magos have very different views on who M is, and have been separated since the death of Santiago. Yet something they have in common is their fierce love for M. 

Finally, the last part of the novel is told by M. The sections leading up to M’s are a slow burn, and M’s narration was my favorite part of the book. M is trying to figure out where he belongs in the shadow of someone else, but M has the added obstacle of not being completely human. He is battling his ever-present hunger for humans, the expectations of his loved ones, his desire to understand humans, and generally fitting in a world not created for him. M is the result of a monstrous decision made by someone else, in the throes of monstrous grief, and he does not know if he is M, Santiago, Monstrilio, a combination, or someone else entirely. 

Monstrilio is a stunning novel that wraps its characters in grief, love, and the persistence of both. It examines the lasting effects of grief and how, if we let it, our own grief can affect those we hold most dear and even turn us monstrous. The novel also explores the binding results of loyalty and acceptance of those we love. Monstrilio features dark themes and is the most gory horror novel I’ve personally read (I haven’t read many). That might be an immediate “no” for some readers, and an immediate “yes” for others; either way, the part horror, part literary meditation on emotions that makes up this novel was unexpected, unsettling, and simply wonderful. Córdova comes out swinging with this debut and I am looking forward to what he releases next. While Monstrilio did make me sad, it is a book that I won’t soon forget.
