When Sophie Thatcher wakes up in a room she doesn’t recognize after a night she can’t remember, she assumes she had too much to drink and went home with a date.

Except… the date is nowhere to be found.

No one is.

The space she finds herself in is completely nondescript—the walls bare, fridge empty. And just when she thought things couldn’t get bleaker or more confusing, she realizes the doors are locked from the outside.

Trapped inside an unfamiliar place and faced with a clock counting down to a mysterious deadline, Sophie tries desperately to recall the hours missing from her memory and formulate a plan to escape, but each attempt proves more futile than the last.

Hidden away from the world and unable to contact the people who would care that she’s missing, Sophie has two questions ringing in her mind: Who would bring her to this place? And why?

When she’s joined in her personal prison by someone she never thought she’d see again, everything changes and the idea of her being a random target instantly vanishes.

Whoever brought Sophie to this place has plans for her and, if she can’t figure out a way to escape before time runs out, her fate may be to remain hidden forever.

Ominous, dark, and completely disturbing, this pulse-pounding thriller from the twisted mind of million-copy bestselling author Kiersten Modglin is unlike anything you’ve listened to before.
