Just finished reading RAIN REIGN by Anne Martin (yes, the Babysitter's Club author). It is a very touching story about an autistic girl who is obsessed with prime numbers and homonyms. When her father gives her a stray puppy, she names him Rain Reign. But she eventually discovers that the dog's previous owners are looking for him, and she must make a very difficult decision. The book reminded me very much of THE CURIOUS INCIDENT OF THE DOG IN THE NIGHTTIME, especially in addressing the bravery needed for kids like that to venture out into the world and deal with other people. I highly recommend it!
