The Chase — L.J. Smith

THEY'RE PLAYING THE GAME OF THEIR LIVES

Why is her boyfriend Tom avoiding her -- while other boys pursue her as never before? Jenny Thornton has changed. So have her friends. Because of Julian, the Shadow Man, who has returned to terrorize them with a new game, a hunting game, Lambs and Monsters. They're the lambs, to be stalked, pounced upon, and lost to the Shadow World forevermore. The monsters are the Lurker, a ghostly wolf, and the Creeper, a phantom snake. One by one, Jenny's friends disappear, leaving behind only a paper doll -- and a riddle with clues about who will be next . . . . Jenny must find Julian's hidden base and save her friends before it's too late. But how can she resist the predatory prince of darkness who has returned to make her his own?
