Keeping the Moon

A plot description of this contemporary problem novel may make it sound like a kind of Cinderella story, but Dessen's (Someone Like You) ironic sense of humor and her knack for creating characters with both quirky personalities and universal emotions set her book apart. Colie's fitness-celebrity mom (a female version of Richard Simmons) long ago motivated her to lose 45.5 pounds, but Colie feels just as insecure as she did when she was overweight, and she is a pariah at school. During Colie's 15th summer, her mother goes on an extended tour of Europe, and Colie is sent to outlandish Aunt Mira in Colby, N.C. There Colie is influenced by a singular group of mentors: the young women next door, Isabel and Morgan, who give Colie a makeover as well as a waitressing job; Mira's young boarder, Norman, who has moved out of his bullying auto-dealer dad's house so he can pursue a career in art; and Mira herself, a greeting-card illustrator who is as enormous and eccentric as she is immune to the ostracism of the locals. As readers will anticipate, Colie begins a happy metamorphosis; unexpectedly, her transformation is interrupted by the arrival of a mean-mouthed schoolmate who is all too eager to cut Colie down. Readers will lap up the snappy dialogue, colorful episodes and unexpected pearls of wisdom. The lessons Colie learns about beauty, none of them new, come across with freshness and vitality. Ages 12-up. (Sept.)
