Some people think that I'm a problem child, that I'm lazy and never pay attention in lessons. But the thing is, I'm not a problem child at all. I'm just a child with a problem.
Felix is struggling at school. His ADHD makes it hard for him to concentrate and his grades are slipping. Everyone keeps telling him to try harder, but no one seems to understand just how hard he finds it. When Mum suggests Felix spends time with his grandfather, Felix can't think of anything worse. Granddad hasn't been the same since Grandma died. Plus he's always trying to teach Felix boring chess. But sometimes the best lessons come in the most unexpected of places, and Granddad soon shows Felix that there's everything to play for.
