Claire O'Toole's mother, Alana, went missing fifteen years ago. That was big news in Pineview, Montana, the kind of town where nothing much ever happens. Then, last year, Claire's husband, David, died in a freak accident — after launching his own investigation into Alana's disappearance. Is Alana dead? Or did she simply abandon her husband and daughters? Claire's determined to find out — and her former boyfriend, Isaac Morgan, wants to help. Although their relationship didn't end well, he still has feelings for her. And yet it isn't until he starts to suspect David's death wasn't an accident that he's drawn back into her life. Together, Claire and Isaac search for answers to the questions that have haunted Pineview all this time. But as they soon discover, someone's prepared to kill so those answers won't be found. . .
