Neither Rose’s dad nor her teachers understand the challenges this bright girl faces due to her obsessive behaviors. Rose makes sense of her world by collecting homonyms and prime numbers, and rigidly adhering to rules. Because of her struggles, Rose is quite lonely—apart from time spent with her empathetic uncle—until her dad brings home a stray dog. In keeping with her love of homonyms, Rose names the dog, Rain Reign (Feiwel & Friends, $16.99). When Rain goes missing after a storm, Rose’s ability to be flexible and her sense of fairness are tested. Newbery Honor award winner Ann M. Martin’s incisive, heartrending story of a resilient girl is ultimately one of hope.  Ages 9-12. MAG
