Eighteen-year-old Raquel isn't eighteen anymore... During Raquel's first semester of college, she witnesses the end of the world, only to wake up in her old room at her parents' house two years in the past. Even worse, it seems she's the only one who remembers-until Chris Lyley, a boy Raquel always thought was a loser, tells her he remembers the catastrophe. Before long, they both discover new abilities. They're able to understand any language and teleport through time and space. If Raquel and Chris can figure out what caused the end of their world, maybe they can stop it.
