The last thing Eider sheriff Shane Hamilton needs is a determined FBI agent in his county. He's already dealing with the fallout over his recent and all-too-close re-election, two gruesome homicides, and a rash of arsons. And personal grief weighs heavily on his soul.

Returning to Eider, Iowa, wasn't part of FBI agent Liza Bartholomew's game plan, but when she learns an elusive scam artist has been seen there, a man she's been tracking for years, she doesn't hesitate to follow the intel. Vengeance for his victims and her career are both on the line, and she won't rest until justice is served. She doesn't expect to be stonewalled by the town sheriff.

It soon becomes obvious to Shane that his and Liza's cases are intertwined, and they're forced to work together, a move that challenges his longstanding vow of not getting emotionally or professionally too close to another woman.

As the body count mounts, Shane and Liza find themselves and everyone they love in the immediate crosshairs.

What will they sacrifice to stop the cold-blooded killer in time?
