A different me by Deborah Blumenthal Book

High schooler Allie, who has long wanted to get plastic surgery, becomes online friends with two other girls who share her obsession. Allie Johnston's secret wish since the day she was twelve is to have her nose done. But she's never told anyone―not her parents, or even her best friend, Jen. But when she starts visiting a plastic surgery discussion board on the Web, she finds people who get her for the first time in her life. Her new friends include two girls her age who share her obsession with changing their faces―but for very different reasons. A sharply written, insightful book about learning to be happy with who we are.
