A killer's game of cat and mouse—but his prey has secrets.

 Keiki Tallerman is a snarky, strong-willed tech prodigy whose life shatters after witnessing the death of her best friend on a remote Pennsylvania mountain.

 Experience dictates she keep her mouth shut, and when detectives knock on her door, she won't hand over evidence until she's identified the assassin. After all, they never found her parents' killer.

 Detective Nolan Garnett knows Keiki is involved in a gruesome murder somehow but can't piece the evidence together. Unable to coerce the meddlesome coed to talk, he doesn't know whether to cuff her or kiss her.

 Survival depends on joining forces to navigate a world of friendship and betrayal where each step could be the last.
