Everyone in Clapham knows the stories. The sealed door at the station. The WWII shelter that goes deeper than it should. The people who come back wrong. Zain knows the stories too. He opens the door anyway. Inside Clapham Deep: eight thousand people sheltered from the Blitz in tunnels that were supposed to be temporary. They left. Something didn't. And in eighty years of silence and darkness, it has learned - how to imitate, how to study, how to wait, and most importantly, that the light doesn't hurt it.
The light feeds it. By the time Zain and his friends find the warnings scratched into the walls - DON'T FEED IT AFTER MIDNIGHT - they are already below the wrong platform, the door is sealed, and the thing below them is no longer just watching. A gripping South London urban horror novel. For fans of found-space horror and monsters that learn.
