Austen Walker, a short fifteen-year-old boy, is about to start his last year at school. To those who know him, he appears an unambitious, unassuming and aimless teenager, but with all his heart he supports his dad in looking after his mum, a locked-in syndrome sufferer. Then out of nowhere, something happens. There's an unknown entity in the house. Pieces are moving on the chess table when backs are turned, but whatever it is, it can play well. This is only the beginning. This thing has lived in Austen's house for over a hundred years and now it needs to return to where it came from. For that, it'll need Austen for The Incredible Adventure.
