Rose Howard is autistic (main character) and she explains her story throughout in her own eyes and way of thinking. She lives with her father and sees her uncle frequently (sweetest man ever). She loves to mention prime numbers, especially in the number of letters in a word and loves homonyms, which she keeps a long list of them for herself. The title comes from the name of her dog Rain, a dog that her father found and later gave it to her as a gift. Rose decided to name her Rain because it has two homonyms: Rain and Reign. Things start to change and Rose makes choices (she always wants to do the right thing) in which questions her own feelings.
