Rose is a little girl with high functioning autism, who lives with her father and her dog, Rain. 
 Rain is a good name, because it has a homonym, reign. Rose is very interested in homonyms, prime numbers, and her dog, Rain. 
 One night, a giant hurricane blows in, and Rose's dad lets Rain outside in it, to use the bathroom. She doesn't return. 
 This book was very sad, but still enjoyable. I'm not sure who I'd recommend it to, because I'd feel bad making anyone else cry. It was a very interesting look, though, into the mind of a special needs child.
