Premonitions

Grace has premonitions. They've haunted her since her parents' death. She doesn't know how to deal with them, and doesn't want to. She never knows whether she's seeing the past, the present, or the future. It just comes to her. Then Grace's best friend disappears. And suddenly the premonitions that have been the bane of her existence become the only way to solve the mystery of where the friend has gone -- and how she can be saved in time.
