Having a roommate at elite Waverly Academy means nightly sleepovers and double the designer wardrobe. But Callie Vernon never really liked late-night girl talk or swapping cashmere sweaters with her younger, rosy-cheeked roomie, Jenny Humphrey. So when Jenny stole her longtime boyfriend, Easy Walsh, Callie didn't feel that guilty about turning right around and kissing him behind Jenny's back. Okay, maybe a little guilty, but it certainly didn't stop her from enjoying it. Now, if only Easy would stop being so irritatingly indecisive and dump Jenny already!While the two roommates are sharing a boyfriend, the rest of Dumbarton's residents are sharing their feelings at the newly founded Women of Waverly club--aka, WOW! Everyone is totally bonding, revealing their most personal secrets, and hugging out their past rivalries. But despite the sharing-is-caring vibe, there are some things these girls aren't spilling--like who's making special late-night trips to the crater . . . and with whom.Now it's only a matter of time before all the newfound girl power explodes into a massive girl fight. But this battle goes well beyond the ivy colored brick walls of Dumberton--it's about who will be Waverly's next It Girl.
