It's been so long since Auden slept at night. Ever since her parents' divorce—or since the fighting started. Now she has the chance to spend a carefree summer with her dad and his new family in the charming beach town where they live.

A job in a clothes boutique introduces Auden to the world of girls: their talk, their friendship, their crushes. She missed out on all that, too busy being the perfect daughter to her demanding mother. Then she meets Eli, an intriguing loner and a fellow insomniac who becomes her guide to the nocturnal world of the town. Together they embark on parallel quests: for Auden, to experience the carefree teenage life she's been denied; for Eli, to come to terms with the guilt he feels for the death of a friend.

In her signature pitch-perfect style, Sarah Dessen explores the hearts of two lonely people learning to connect.
