The Captive - L.J. Smith
Continuing from the previous book, Cassie is being blackmailed by Faye ever since she spied on her and Adam kissing. Cassie struggles with herself not to tell Diana, her best friend and Adam's girlfriend, but she decides against it, since it would makes things worse. Faye forces Cassie to dig up the crystal skull that gives the Circle's members odd visions. Students continue to be murdered, and Faye is elected coven leader, since she forced Cassie to vote for her against Diana, whom everyone assumed would win.
