Felix Yz
by Lisa Bunker
A 13-year-old fused with an alien races a 29-day countdown — identity, love, and loss in diary form
The story
Felix Yz has been fused with an alien consciousness named Zyx since age three. In 29 days, a dangerous procedure will either separate them — or kill Felix. As the countdown ticks, Felix navigates a first crush on a boy, his grandparent's gender identity coming out, and the possibility of losing the only companion who's always been inside his head.
Age verdict
Best fit: 12-14. Still works for thoughtful 11-year-olds and teens.
Our take

What stands out
Each audience's top 3 dimensions. Out of 30 scored per book.
Kids love
- Heart-punch Strong
[book] Final Procedure chapters (Ch 38-41): Zyx's death as Felix lives, Felix learning to accept his queer identity, Grandy's pronoun revelation. Multiple devastating moments matching Bridge to Terabithia (9) territory but spread, not concentrated.
- First-chapter grab Strong
[book] Ch 1 hooks with 'My name is Felix Yz, and in 29 days I will die or become something other than human.' Diary frame + countdown + fused-with-alien premise establishes voice and stakes immediately.
Parents love
- Stereotype-breaker Strong
[book] Nonbinary grandparent (Grandy) who comes out mid-book, queer male protagonist, Asian-American family, alien consciousness as metaphor for otherness. Rivals George (8) for representation breadth.
- Emotional sophistication Strong
[book] Grief for absent father, anticipatory grief for Zyx, first-crush anxiety, identity fear — layered emotions held simultaneously. Matches Bridge to Terabithia (8) sophistication.
Teachers love
- Discussion fuel Strong
[book] Gender identity, sacrifice ethics, disability as metaphor, grief, queer coming-of-age — 30+ natural discussion openings. Matches Wonder (9) and George (8).
- Empathy & self-awareness Strong
[book] Grandy's gender journey, Felix's queer awakening, Zyx's sacrifice all model empathy-building. Rivals Wonder (9).
