DS is 15 and a very able but reluctant reader. He's absolutely obsessed with cars (particularly F1 and touring car racing at the moment) and also very interested in planes and aviation. He's read and enjoyed all of Chris Ryan's teen series, but other than that he only really reads Haynes Manuals and F1 magazines. I'd like to get him reading more fiction before his English Language GCSE, though. He only likes books that are grounded in reality - no fantasy or futuristic sci-fi/dystopia type stuff (tried Alex Rider, Maze Runner, Hunger Games but couldn't get into any of them). Any recommendations?
