Gr 9 Up-This fourth entry in the series jumps right into action as one of the "Billings Girls" watches her current boyfriend being hauled away for the murder of her former one. Though Reed Brenner lives in the prestigious Billings Hall and is best friends with the top group, she is not like the other girls. For one thing, she's a scholarship student and for another, she believes Josh is innocent. While the rest of the school tries to figure out ways to party off campus, Reed becomes obsessed with finding the real killer. She discovers an ill-advised affair, a jealous debutante, and more secrets than money at Easton Academy. The novel is a quick read, complete with plenty of pop-culture references. The suspense grows along with Reed's paranoia. Much of the tension comes from the protagonist's relationship with the Queen Bee, Noelle. She doesn't trust her but is drawn to her nonetheless. Readers will feel the same way. Give this book to teens who want light reading and a little mystery. Sadie Mattox, DeKalb County Public Library, Decatur, GA
