Book 4 of Wolf's-own

Fen Jacin-rei finds himself again on the run after discovering the reality of what he is and why the gods won't let him go. His one source of support, Kamen Malick, is suddenly unavailable, and now hounded and chased by ghosts who want to drive him into insanity and keep him there, Fen will have to face life all alone.

...Or maybe not. Old enemies and new allies seek to control Fen, now known as "Kamen's Untouchable." It's going to take everything Fen's got to figure out who he can trust—and who he should fear. It might take more than what Fen's got to discern who is even real.
