"Gr 7 Up--Toni Valentine has always been one of the guys. She's more comfortable in basketball shorts and sneakers than in skirts and heels, and her idea of a good time is attempting to capture evidence of Champ, the monster who supposedly lives in her town's lake. But after a harmless prank lands her in an all-girls school for senior year, Toni feels she is losing touch with her guy friends and fears what the future may bring. In an attempt to bring her and her buddies back together, she starts the Toni Valentine's Rent-A-Gent Service and begins loaning out her friends for high-paying fake dates. In the process, Toni meets Emma, her first female friend, and develops romantic feelings for her best guy friend. This is a fun, fast-paced story about growing up, falling in love, and embracing change. It is a great weekend read for teens looking to lose themselves in a story that will give them a good laugh along with some serious themes. VERDICT A lighthearted, feel-good book for pure enjoyment."--Betsy Davison, Cortland Free Library, Library Journal
