There are three things to know about Maia: 1. Ever since her mother left, she has struggled with depression, which once got so bad she had to go to an institution for a while. She doesn't want to go back. 2. Maia is certain that if she finds her mother, and the two of them can talk about whale songs and constellations for a while, then everything will go back to normal again. 3. She is in love with Billy, the handsome and brooding boy who lives in the group home in town. Billy didn't seem to know Maia existed until now. When Maia sets off on a road trip in search of her mom, Billy unexpectedly comes along. They drive up the East Coast, stopping along the way for lobster rolls and lighthouses. That's when Maia learns Billy has dark secrets of his own, and that he too wants to outrun his past. But what will the future hold if they reach their destination?
