I Am the Wallpaper — Mark Peter Hughes

Thirteen-year-old Floey Packer feels like she's always blended into the background. After all, she's the frumpy younger sister of the Fabulous Lillian, a girl so popular and spontaneous that their house is always packed with a gaggle of admirers. But when Lillian suddenly gets married and heads off on a month-long honeymoon, Floey decides it's her time to shine. Armed with her trusty diary, some books on Zen philosophy, and a jar of Deep Wild Violet hair dye, Floey embarks on a self-improvement mission -- with excellent results. People are finally noticing her, especially the boy who really counts. But then disaster strikes.

Are people noticing Floey because she's so fabulous -- or because her evil cousins posted her diary on the Internet? And how will Floey ever repair the damage?
