Make Every Word Count

With no warning, Mike and his too-perfect older sister are transported to a world where people use magic instead of science. There he discovers that an evil wizard is using mind control to take over the planet. Of course, this could be an opportunity for a brainy, talkative, middle school kid with Asperger Syndrome who loves maps and military strategy games. But how can he use his smarts and skills when he falls under a spell that lets him say only five words every five minutes? How does a guy who's used to saying everything lead an uprising when he can hardly say anything? His only chance is to make every word count. (Note: Asperger Syndrome is also known as Level One Autism)
