Surviving middle school is a fulltime job, especially for Willa Shisbey—unlucky Number Thirteen. Willa is the thirteenth person in the world documented with something called H-SAM (Highly Superior Autographical Memory.) Willa can recall, with computer accuracy, every crummy day of her loser life beginning the moment her birth mother dumped her off at an orphanage, one day after her first birthday. But after a few rough starts as the nerdy new girl at Triton Middle School, Willa’s bad luck begins to change when she befriends a new student on campus—a boy with cerebral palsy who sits in a wheelchair, and Willa sets out to prove to her classmates that it just might be cool to be kind.
