In a twisty and provocative thriller debut, Elle Owens tells the story of a young mother whose husband vanishes without a trace, and their shared playlist holds the only key to bringing him back.

When her husband goes missing, Marissa Creighton fears the worst. Tell me you trust me was the last thing Ethan said to her, and she'd shrugged it off. Now she can't get those words out of her head.

Marissa's family has always been her rock. But when they come to help her with eighteen-month-old Logan, their overprotectiveness borders on oppression-occupational hazard of the family's surveillance business, or is it? Seeking comfort in the playlist she and Ethan share, Marissa is shocked to find a new song there: "Trust Me." She's certain it's a message.

Using song titles as code, she and Ethan start communicating back and forth. But she still doesn't understand why he left. While his messages point to incriminating documents, her family uncovers evidence of an affair. But their discoveries come with their own baggage, including personal threats, secret bank accounts, and dusty surveillance devices. All the while Marissa wonders whether she'll ever learn the truth-or see her husband again.
