I went into Underneath with curiosity, especially after learning that it took Lily Hoang eight years to write. Unfortunately, I found the result disappointing, upsetting, and, at times, offensive.
The book was difficult to follow, both structurally and emotionally. The prose felt disjointed, the narrative hard to engage with, and the characters frustratingly underdeveloped. As someone who shares the same weight as the main character, Martha, I was especially disturbed by how fatness was portrayed. The language used to describe her body and habits felt unnecessarily cruel, stereotypical, and rooted in fatphobia. I do not identify with a character whose entire identity is reduced to being “disgusting” simply for existing in a larger body, nor do I relate to the exaggerated, dehumanizing assumptions about diet and physical ability that the book perpetuates.
The depiction of regional culture also raised concerns. Though the story is set in New Mexico, the characters read like caricatures of the Deep South, with a “Southern Gothic cosplay” that felt more like Georgia (where the real-life crimes occurred) than the Southwest. As a Southerner, I found the portrayal grating and inauthentic.
Even more troubling was the way the author handled the real-life murders the book draws from. Creative liberties are expected in fiction, but in this case, they felt excessive and disrespectful to the real people involved. Rather than illuminating the complexity of the crimes, the novel leaned heavily into a sensationalized and problematic portrayal of the perpetrator.
The extensive list toward the end, 300+ reasons why Martha turned out the way she did, appeared to be a last-ditch effort to humanize her. But it came too late and felt more like a justification of trauma than an exploration of accountability or empathy. Martha is portrayed not as a murderer first, but as someone inherently repulsive due to her appearance, something that is deeply unsettling and offensive.
Overall, Underneath reads like a project born of internalized body dysmorphia and unresolved personal issues. Instead of challenging fatphobic narratives, it reinforces them. Rather than offering insight into trauma or crime, it distorts them. I walked away from this book not with empathy, but with frustration and discomfort.
I cannot recommend it.
