Rose Howard is obsessed with homonyms. She's thrilled that her own name is a homonym, and she purposely gave her dog Rain a name with two homonyms (Reign, Rein), which, according to Rose's rules of homonyms, is very special. Not everyone understands Rose's obsessions, her rules, and the other things that make her different -- not her teachers, not other kids, and not her single father.
When a storm hits their rural town, rivers overflow, the roads are flooded, and Rain goes missing. Rose's father shouldn't have let Rain out. Now Rose has to find her dog, even if it means leaving her routines and safe places to search.
"Rose has a diagnosis of Asperger’s, and her world of comforting homonyms, rules and prime numbers is repeatedly challenged by social interactions of which she has no innate understanding. Newbery Honor author Martin crafts a skillful tale that engages readers’ sympathy for everyone portrayed in the story, even Rose’s garage-mechanic, hard-drinking single father....Martin has penned a riveting, seamless narrative in which each word sings and each scene counts. There is no fluff here, just sophisticated, emotionally honest storytelling." -- Kirkus Reviews
