Shadowland

The inaugural installment of The Mediator series introduces high school sophomore Suze, who, in her words, has ""this unfortunate ability to communicate with the dead."" As a ""mediator,"" the girl helps ghosts put unresolved issues to rest so they can move on to the next world. When her mother remarries, Suze moves from New York City to California, where she and her three stepbrothers attend a Catholic academy headed by a priest. Conveniently, the priest is also a mediator (the first of her kind that Suze has ever met). During the course of this rather repetitious and intermittently sluggish caper, Suze encounters two ghosts: a handsome young man from the 19th century who haunts her bedroom and a girl who was a student at the academy until she killed herself when Bryce, her boyfriend, broke up with her. As Suze attempts to protect Bryce from the angry apparition's wrath, the ghostly girl grows determined to get revenge on both her former beau and Suze. Suze finally resorts to an exorcism to get rid of her. As a narrator this teen is a bit too tough-talking and cocky to be credible. Still, the intriguing premise of a 16-year-old with a sixth sense may stand more than a ghost of a chance at snaring teen readers. Ages 14-up. (Nov.)
