Rose is disappointed with her life, though she has no reason to be - she has a beautiful family and a perfectly nice house in the suburbs. But to Rose, this ordinary life feels overshadowed by her other life - the one she leads every night in her dreams. After a childhood accident, Rose's dreams take her to a wondrous island fraught with adventure. On this island, she has never been alone: she shares it with Hugo, a brave boy who's grown up with her into a hero of a man. But when Rose stumbles across Hugo in real life, both her real and dream worlds are changed forever. Here is the man who has shared all of her incredible adventures in impossible places, who grew up with her, even if they aren't what either one imagined. Their chance encounter begins a cascade of questions, lies, and a dangerous obsession that threatens to topple everything she knows. Is she willing to let go of everything she holds dear to understand their extraordinary connection? And will it lead her to discover who she truly wants to be?
