Drew is a bit of a loner. She's usually hanging out in her mother's cheese shop. She has a pet rat, her dead dad's Book of Lists, and a crush on Nick,the surf bum who works behind the counter. It's the summer before eighth grade, and Drew's days seem like business as usual - until one night after closing time, when she meets a strange boy named Emmett Crane in the alley behind the shop. Who he is, why he's there, where the cut on his cheek came from, and how he gained his limitless knowledge of rats are all mysteries Drew wil untangle as she and Emmett are drawn closer together and Drew enters into the first true frendship of her life.
