Watch me disappear

the long version

"Lizzie's father has moved the family around every few years to advance his career, so she has never had a chance to develop the kind of "BFF" relationships she thinks most kids have. She's bracing herself for another lonely year at her third high school when her neighbor Maura gets sick of watching her little brother when she could be partying. Thanks to Maura's plotting, Lizzie becomes everyone's new favorite babysitter. Seeing her opportunity, Lizzie decides to break her mother's rules by using Maura's computer to create a secret Email address and Facebook account. She is quickly friended by Missy, a fellow transfer student as eager for a friend as she is. Things are looking up for Lizzie until Maura's ex-boyfriend Paul sets his eye on Missy. Caught between her new best friend and the neighbor whose friendship promises instant popularity, Lizzie doesn't know what to do--because she's fallen for Paul, too."--Page 4 of cover.
