In off-season Blackpool, people disappear when they notice the wrong things.
Days repeat. Conversations change. Faces vanish. Records no longer match what people remember. Mick Holden knows something is wrong. Events he remembers have not happened. People he has met no longer exist. When he turns to journalist Alice Whittaker, he finds someone already following the same pattern. Together, they begin to uncover a Blackpool that is being rewritten around them. Evidence disappears. Memory cannot be trusted. The more they learn, the harder it becomes to know which version of events is real. Then the fractures begin to point backwards to Blackpool in 1895. The past should be fixed. It isn't. As the disturbances spread, Mick and Alice must work out what connects the two periods before the evidence changes again and before they become part of what has been forgotten. Some systems are built to forget. Some places do not want to be remembered.
