She profiles killers for a living.
She knows their patterns, their tells, their lies.
Now one of them has found the perfect way inside her mind.
Dr. Emma Walters has spent her career dissecting the psychology of murder from a safe distance: case files, crime-scene photographs, the cold logic of other people's cruelty.
Then a string of women is found dead across Chicago, each of them certain she had finally found love. The killer courts his victims first. He learns them. And he is very, very good at it.
Emma's new relationship with Alex, a charming artist who understands her better than anyone ever has, offers the comfort she never lets herself want... until his insights start landing a little too precisely.
Her closest friend Claire sees it before she does. "It isn't love I see," she tells Emma. "It's possession."
As the bodies accumulate, the killer stays a step ahead of the task force. He anticipates their moves. He seems to know exactly how a profiler thinks.
Because someone is using Emma's expertise against her. And by the time Detective Hopkins lays the evidence on the table, the truth is worse than any profile she has ever written.
A razor-sharp psychological thriller about obsession, trust, and the terrifying line between love and manipulation, where catching the monster means going somewhere the case files never prepared her for.
