"Marcus Good Boy" gives an insight into the world of Autism and Hyperlexia, by answering questions that little kids may have.

Marcus is a three-year-old who writes and reads well. He enjoys playing with letters and numbers, does not care for traditional toys, and prefers playing alone. His siblings were curious about the fact that he could read and write well, but he would not speak to them or play with them. They had plenty of questions for their mother, who answered them in ways suitable for young and old minds alike.
