David Greenberg, would-be future anchor of The Daily Show, enters middle school with problems: Longtime best friend Elliott has abandoned him for new, nastier and bigger friends, David hasn’t spoken with his runaway mother in months and he’s dumbstruck by a sudden crush on adorable, peppermint-scented redhead Sophie Meyers. Sophie shares David’s funny videos—in which he apes Jon Stewart’s style and tone as only a burgeoning sixth-grade comedian can—with her homeschooling friends, launching David into sudden Internet fame. Real life intrudes in the forms of merciless teasing by Elliott and his friends and David’s desperate desire to connect with his mentally ill mother, who abandoned the family for life in rural Maine two years ago. Sensible and loving win out over mean and bullying, giving David space to balance his real and online lives. Gephart maps the hormonal, emotionally torturous terrain of pubescent boyhood with realistic dialogue, well-developed secondary characters and age-appropriate humor and insight, placing this title in the same august league as Jordan Sonnenblick’s Girls, Drums and Dangerous Pie (2004). (Fiction. 10-13)
