5th to 8th grade. Sara Cassidy writes a fast paced, inspirational tale of teenage eco activism in hi-lo book Slick. Liza is a teenager upset over her parent's divorce and her mother's new boyfriend. She researches the oil company that the boyfriend works for, and finds out how it is avoiding making reparations to Guatemalan farmers. She channels her feelings into organizing an activist group called GRRR! (Girls for Renewable Resources Really!). She plans out a demonstration on that oil company, but finally discovers that the new boyfriend is made of better stuff than she had suspected. In addition to the creative plot, Slick is appealing for its humor and irresistible spirit. Easy and fun to read, Slick will be a hit with young patrons. This book is highly recommended to public and middle school libraries. ( )
