Description

From Possess and Ten author Gretchen McNeil comes a deliciously eerie science-fiction horror story in the tradition of Lisa McMann's Wake trilogy and the movie Sliding Doors.

Josie Byrne's life is spiraling out of control. And just when she thinks it can't get worse, she wakes to an image of herself in the bedroom mirror. Except it's not her at all—the girl in the mirror is blonder and prettier. And her name is Jo.

The two girls are doppelgängers whose universes overlap every twelve hours at 3:59. Fascinated by Jo's perfect world, Josie jumps at the chance to pass through the portal and switch places for a day.

But Jo's world is far from perfect, and the stuff of nightmares lurks around every corner. And when Josie finds herself trapped there, her life becomes more dangerous—and more deadly—than she ever imagined.

Trapped in Another World: One day was the deal. But when the portal back to her own universe closes, Josie is stranded in a world that’s anything but perfect, with no way home. Best Friend Betrayal: Josie’s life is already a wreck after catching her boyfriend with her best friend. But that betrayal is nothing compared to the one that leaves her fighting for her life. Quantum Physics Thriller: Based on real scientific theories, this isn’t just a scary story—it’s a mind-bending exploration of what could be lurking on the other side of the mirror. Creature Feature: The darkness in Jo’s world isn’t empty. It’s filled with the Nox, terrifying creatures that hunt by night and leave a trail of bodies in their wake.
