Twelve-year-old Westin Hopper gets in trouble--a lot. At home, at school, at his grandparents' house....His ADHD always seems to mess with his brain, making him do impulsive things. So when Westin finds a magic bag that makes his thoughts come alive, he thinks it's the ticket to fixing his life. Instead, his wandering brain strikes again, conjuring up a mini T. rex, an army of headless plastic men, and a six-inch Thor. Now they all live in his bedroom, eating lunchmeat, wreaking havoc, and growing. And Westin doesn't know how to make them go away. He enlists his fellow social outcast, Lenora, to help him make things right. Lenora helps Westin realize that his talent for drawing could be the key to solving his problems. If Westin can focus while drawing, maybe he can learn to control the magic and get rid of the creatures in his room. But he'd better learn quickly. Tiny T is growing--and fast.
