A mother will do anything to protect her baby . . .

WHEN A KILLER HAS NOTHING TO LOSE
The crime scene is as puzzling as it is brutal. Paul and Brindel Latham are found dead in their beautiful San Francisco home, each the victim of a gunshot wound to the head.

THERE'S EVERY REASON
For Detective Regan Pescoli, news of her sister's death brings grief and guilt. She and Brindel weren't close, and Pescoli barely knows her teenage niece, Ivy, who lands on her doorstep in Grizzly Falls, Montana. Though Pescoli is on maternity leave, she's soon deeply involved in a very personal investigation.

TO BE AFRAID . . .
But as the list of suspects keeps growing, so does the body count. And Pescoli is about to find that both her and her loved ones are at the mercy of a killer who'll go to any lengths to see her suffer . . .
