Suspense/thriller with a side of romance. Lots of twists in the Investigation of a serial killer. The crimes (murders, kidnapping, sexual assault) are off-page, though the discovery of dead bodies is descriptive.  

FBI agent Snow is a former child prodigy who grew up to be a profiler and agent with off-the-chart abilities to remember details but not relate well to humans. Not sure if she is purposefully written as a neuro-divergent character or just reads like one? Her inner monologue includes multiple references to trying to relate to emotion and dialogue between characters is stilted.
