Felix Yz

Overview

Felix Yz has lived with a stowaway since he was three: a being from a higher dimension, accidentally bonded to him when his father's experiment misfired. Now thirteen, Felix is running out of time. The fusion has kept him from growing up normally, and a dangerous medical procedure has been scheduled to pull the two apart—though there's a real chance it kills them instead.

The novel unfolds as Felix's own blog, written in the countdown to that operation. He records the texture of ordinary adolescence alongside the extraordinary circumstances surrounding him: a tense rivalry with a classmate, a nervous crush, and the steady presence of his family. But the days leading up to the Procedure grow stranger, pulling in a visiting chess Grandmaster, buried family history, and an impulsive journey that takes Felix away from everything familiar.

Written as a direct, confiding first-person record, the book balances humor with real stakes, letting readers sit inside Felix's head as he reckons with an ending he can't predict.

A Story About Connection and Separation

At its core, Felix Yz is less interested in science-fiction mechanics than in the emotional weight of being permanently entangled with another consciousness—and what it costs to imagine letting go. The diary format gives the book an intimate, unfiltered quality: Felix's voice is funny and self-aware even as he faces mortality, and that tonal mix is part of what makes the book distinctive within its genre.

The novel also threads in Felix's blindness and his family's makeup, folding questions of identity and difference into the larger premise of two beings sharing one body. Rather than treating those details as separate issues, the book uses them to reinforce its central idea: that individuality and connection aren't opposites, and that the people and traits that make someone "different" are inseparable from who they are. The approaching Procedure becomes a lens for thinking about autonomy, risk, and what people owe the relationships that have shaped them.

Why Felix Yz Has Been Challenged

Objections to this title have generally centered on whether its content is suitable for the younger readers who make up its target audience, rather than on the central premise of the alien fusion itself. Some challenges have pointed to the book's inclusion of a transgender character and frank treatment of gender identity, arguing that the subject matter belongs in different sections of a library or shouldn't be presented to middle-grade readers without parental context. Others have taken issue with Felix's candid, diary-style reflections on his crush and adolescent anxieties, viewing the blog format's unguarded voice as more mature than expected for its shelving. Within this catalog, the book has been the subject of challenge activity in 1 state and 1 school district—a reminder that even a single objection can shape what students are able to access.
