Un Wholly by Neal Shusterman

Book Two of the Unwind Dystology

In a dystopian world where unwanted teens are salvaged for their body parts, a group of resilient young individuals fights for survival and freedom. As they navigate a society that devalues their existence, they form unexpected alliances and confront moral dilemmas that challenge their understanding of humanity. With the threat of being "unwound" looming over them, they must outsmart the system and find a way to reclaim their futures, all while grappling with the ethical complexities of their own identities and the choices they must make to stay alive.
