On a soft summer night in Vermont, 12-year-old Lisa went into the woods behind her house and never came out again. Before she disappeared, she told her little brother, Sam, about a door that led to a magical place where she would meet the King of the Fairies and become his queen.
15 years later, Phoebe is in love with Sam, a practical, sensible man who doesn’t fear the dark and doesn’t have bad dreams --- who, in fact, helps Phoebe ignore her own. But suddenly the couple is faced with a series of eerie, unexplained occurrences that challenge Sam’s hardheaded, realistic view of the world. As they question their reality, a terrible promise Sam made years ago is revealed --- a promise that could destroy them all.
