Seventeen-year-old Aaron has grown up at the Cut.

Without a tracker, he has no place in society, but the thought of hiding at the rebel base forever feels like torture.

So when the Cut's spy turns up dead and leadership calls for a replacement, Aaron eagerly volunteers. Armed with a false tracker and a name he can barely recall, he steps into the world he's long been denied.

His mission: infiltrate the Corps, the very organization hunting his people. Success could change everything for the Cut-but failure could cost everyone he loves.
