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. Struggling with Asperger's, Rose shares a bond with her beloved dog, but when the dog goes missing during a storm, Rose is forced to confront the limits of her comfort levels, even if it means leaving her routines in order to search for her pet.
