Chilling story of a lost astronaut on an alien artefact from Arthur C. Clarke award-winning Adrian Tchaikovsky. My name is Gary Rendell. I’m an astronaut. When they asked me as a kid what I wanted to be when I grew up, I said, “astronaut, please!” I dreamed astronaut, I worked astronaut, I studied astronaut. I got lucky; when a probe sent out to explore the Oort Cloud found a strange alien rock and an international team of scientists was put together to go and look at it, I made the draw. I got even luckier. When disaster hit and our team was split up, scattered through the endless cold tunnels, I somehow survived. Now I’m lost, and alone, and scared, and there’s something horrible in here. Lucky me. Lucky, lucky, lucky.

Harry Bodie’s been called into the delightful fantasy world of his grandmother’s beloved children’s books. It’s not delightful here at all. All roads lead to Underhill, where it’s always winter, and never nice. Harry Bodie has a famous grandmother, who wrote beloved children’s books set in the delightful world of Underhill. Harry himself is a failing kids’ TV presenter whose every attempt to advance his career ends in self-sabotage. His family history seems to be nothing but an impediment. An impediment... or worse. What if Underhill is real? What if it has been waiting decades for a promised child to visit? What if it isn’t delightful at all? And what if its denizens have run out of patience and are taking matters into their own hands?
