I like Unrest. It was different and sophisticated and obviously for the young adult market. 17 year old Elliot is struggling with life after his brush with death in hit and run accident. He can, apparently see, hear and feel ghosts during his sleep and periods of sleep paralysis. He takes matters into his own hands by getting a job at a haunted museum, meets a girl there, and discovers more than he bargained for. A good page turner, with some unexpected twists, and a grisly but satisfying ending.
