Things are already looking a little funny to Nick Hartley after he loses yet another fight with Harry Buncher--and gets his head bashed into a wall in the bargain. So he is less confused than he ordinarily would when he meets Moe Nagic, a homeless man with a puzzle and a secret to sell. Moe offers Nick a way to visit Trokeville, the world that exists at the edge of the picture puzzle. Nick has to go there, if he's ever going to change the way his life is going. But he soon discovers the devastating danger of the journey: His mind could leave him stranded there, with no way of returning. A taut psychological thriller about a boy who tries desperately to stop failing.
