The secrets of autism.

Abstract

Tommy Barrett is a dreamy-eyed fifth-grader who lives with his parents, twin brothers, two cats and a turtle in San Jose, Calif., the heart of Silicon Valley. He's an honor-roll student who likes math and science and video games. He's also a world-class expert on Animorph and Transformer toys. They're like cars and trains and animals that transform into robots or humans — I love them! he shouts exuberantly.
