Addie Douglas is the definition of lame. She's sixteen years old, shy, a bit of a nerd, and hasn't done half the things normal teenagers do. She's never been to a high school dance, never been kissed, and she's scared of just about everything. When her best friend dies, he leaves her a list. It's not just any list. It's a list of things that Addie needs to do before she's twenty. To step out of her shell and live a little. A sort of bucket-list. Addie is a little skeptical that she'll have courage enough to complete his list. But, after all, it is his dying wish. And who could say no to someone as wonderful as Sam Tallsworth?
