Wren Calder has never been easy to read. She prefers it that way. When a stranger sits down across from her in the university library and says her full name like it is something he has been carrying for a while, she does not run. She asks how long he has been looking for her. His answer is precise, unsettling, and completely honest — which makes it the most dangerous thing anyone has ever said to her. Cael is the kind of man rooms adjust for. Wren is the only person in his world he cannot read at all. What she is, what she carries inside her without knowing it, has made her a target for a faction that collects people like her — and does not return them. His solution is a fake relationship. Her condition is the truth. Neither of them gets everything they asked for. But as the lines between performance and reality begin to dissolve, Wren starts to wonder whether the most illegible person she has ever encountered has been reading her all along — and Cael begins to understand that the one variable he cannot govern is the only one that has ever mattered. Some rules exist to protect people. Some exist to protect power. And some people — the rarest kind — were never meant to be governed at all.
