In 2012 one of Keith Stuart's two sons was diagnosed on the autism spectrum. The ramifications felt huge. But then Keith and both boys started playing videogames together - especially Minecraft. Keith had always played games and, since 1995, has been writing about them, first for specialist magazines like Edge and PC Gamer then, for the last 10 years, as games editor for the Guardian. The powerful creative sharing as a family and the blossoming of communication that followed informed his debut novel, A Boy Made of Blocks.
