Sixteen-year-old Maguire knows the universe is against her. No matter how many charms she buys off the internet or good luck rituals she performs each morning, horrible things happen when she's around. Like that time the roller coaster jumped off its tracks. Or the time her brother, father, and uncle were all killed in a car crash—and Maguire walked away with barely a scratch.

Despite what her therapist tells her, Maguire thinks it’s best to hide out in her room, far away from anyone she might accidentally hurt. But then she meets Jordy, an aspiring tennis star who wants to help her break her unlucky streak. Maguire knows that the best thing she can do for him is to stay away, but it turns out staying away may be harder than she thought.
