Gr 5-8--Emma-Jean Lazarus, a highly logical problem-solver, is once again meddling in the "messy" lives of her fellow seventh graders in Lauren Tarshis's sequel (2009) to Emma-Jean Lazarus Fell Out of a Tree (2007, both Dial; Listening Library, 2007). The upcoming middle school dance has contributed to an outbreak of Spring Fever. Even Emma-Jean's mother and teachers seem to have been bitten by the love bug. While trying to understand her own feelings for a certain basketball player, Emma-Jean helps Colleen uncover the writer of an anonymous love note. Well-drawn adolescent characters are further strengthened by Mamie Gummer's spot-on voices. She even adopts different narration voices, alternating between chapters focused on flighty, emotional Colleen, and rational Emma-Jean. This title can stand alone since enough background material is provided. Emma-Jean is a quirky, winning heroine, and this satisfying story will find its niche with careful teen readers who enjoy character-driven stories, and especially with fans of the first title.--Richelle Roth, Boone County Public Library, Florence, KY[Page 54].
