A Montana ex-cop becomes the target of a vengeful killer’s viral guessing game in a propulsive novel of suspense by a bestselling and award-winning author.

A killer dubbed the Confession Artist is posting sketches of potential victims on social media. And paranoia spreads as strangers across the nation admit to their sins—fearing the consequences: You have six days to confess or die.

Then former cop and first-year PI Crosbie Mitchell sees a sketch that bears a striking resemblance to her. How can that be? She’s a nobody from Flathead Valley, Montana. Crosbie dismisses it as an unnerving coincidence. If not for one unmistakable detail that makes the threat hard to ignore. When the FBI is contacted, they are convinced that Crosbie is the next target. So is she.

Crosbie has six days left to fess up online to something plaguing her conscience. But even if she wanted to play the killer’s game, she has more than one secret. And if she ever dares to expose them for the world to see, the truth will destroy her. That’s exactly what the Confession Artist wants.
