Rules Teacher's Edition

Twelve year olf Catherine just wants a normal life. Which is near impossible when you have a brother with autism & a family that revolves around his. She's spent years trying to teach David the rules from a 'peach is not a funny-looking apple' to 'keep your pants on in public' - in order to head off David's embarrassing behaviors. But the summer Catherine meets Jason, a surprising, new sort of friend, & Kristi, the potential next door friend she's always wished for, it's her own shocking behavior that turns everything upside down & forces her to ask: What is 'normal'?
