Oliver lives in a world where at some point in their lives, everyone receives a Deathday Letter, a letter that kindly lets you know you have twenty-four hours left to live. Abraham Lincoln received one, Heath Ledger received one, and on an otherwise typical Thursday morning, fifteen-year-old Oliver Travers receives one. Bummer. With his best friend by his side, Ollie has one day left to live life to the fullest, go on every adventure possible…and set things right with the girl of his dreams.
