When 16-year-old Lucy McGowen goes under sedation for a routine dental procedure, she hopes to come out of it free of pain. Instead, she wakes up in an alternate version of her life―a reality in which her secret hobby is out in the open, her own parents feel like strangers, and her boyfriend doesn’t even know her name. Navigating her new world is hard enough, but then Lucy begins getting cryptic messages from a mysterious sender with unfinished business. She has also acquired a new habit―sleepwalking―and with each episode, she finds herself in increasingly bizarre situations. She doesn’t know if luck has landed her in this revamped version of reality―or if she was somehow chosen―but one thing is clear: she must uncover the truth about how it’s all connected before she loses herself completely. Will Lucy find a way back to her other life . . . or will she create a new world that she can truly call her own?
