Nothing is the same for Joff this summer. His dad is ill, his mam is working, there's a new kid in town. He can't wait to escape each day and explore with his dog Jet. But there's one place he's not allowed to explore. Above the town sits the Chapel of Doom, ancient and crumbling, with its warning signs and the legend of the Falling Boy. And when Joff's adventures take him beyond the boundaries he discovers something unexpected, something truly magical.
