From Newbery Honor author Ann M. Martin, who wrote the Baby-sitters Club series, comes a New York Times-bestselling middle grade novel about a girl, her dog, and the trials of growing up in a complicated and often scary world.

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.


“A story about honorable living in the autistic narrator genre that sets the bar high. . . . Martin has penned a riveting, seamless narrative in which each word sings and each scene counts.” —Kirkus Reviews, starred review
