Josie Byrne' s life is spiraling out of control. Her parents are divorcing, her boyfriend, Nick, has grown distant, and her physics teacher has it in for her. When she' s betrayed by the two people she trusts most, Josie thinks things can' t get worse. Until she starts having dreams about a girl named Jo. Every night at the same time— 3:59 a. m.
Jo' s life is everything Josie wants: she' s popular, her parents are happily married, and Nick adores her. It all seems real, but they' re just dreams, right? Josie thinks so, until she wakes one night to a shadowy image of herself in the bedroom mirror— Jo.
Josie and Jo are doppelgä ngers living in parallel universes that briefly overlap every twelve hours at exactly 3:59. Fascinated by Jo' s fabulous life, Josie jumps at the chance to cross through the portal and switch places for a day. But Jo' s world is far from perfect. Not only is Nick not Jo' s boyfriend, he hates her. Jo' s mom is missing, possibly insane. And at night, shadowy creatures feed on human flesh.
Josie is desperate to return to her own life. But there' s a problem: Jo has sealed the portal, trapping Josie in this dangerous world. Can she figure out a way home before it' s too late?
From master of suspense Gretchen McNeil comes a riveting and deliciously eerie story about the lives we wish we had— and how they just might kill you.
