Fifteen-year-old Lucy's world is rocked when her father confesses to her and her sister that they have a half brother, the result of a brief affair.
Though their mother has been aware of the existence of Thomas, who's 8 and lives in their same New Jersey town, for many years and has made her peace with her husband's infidelity, Lucy reels when she learns about him. Her realistically described reaction of fury and indignation builds until she finally embarks on an impulsive road trip without telling her parents, ending up at her larger-than-life grandfather's house in Maine. This family drama is appealingly narrated in Lucy's wry, confessional voice, and a romance she stumbles into with her friend's stoner brother is sweetly fumbling and awkward. All the major characters seem to be white; musings about the ethnicities of various people Lucy encounters while on her clandestine trip, including a passage in which she wonders whether her own implicit bias might be at play in an interaction she has with a black man, underscore her new determination to seek out answers to questions that have gone unasked in her sheltered upbringing.
A poignant, character-driven coming-of-age novel that, despite a too-tidy ending, will appeal broadly to teen readers. (Fiction. 14-18)
