Limbo

This is set partly in the fantasy world of Limbo, with its castle, king and queen, wizard, and unending night; and otherwise primarily on Hove seafront amongst supposedly normal human beings perpetually drawn into ludicrous situations.

Both venues are under threat when the Prophecy starts to come to pass, heralded by a shower of garbage-eating clams broken loose from a massive spaceship of the far future. What is happening is that the hoop of time is beginning to break up ... till the denizens of Limbo and Hove increasingly merge, and this composite place is eventually overrun by monsters, dinosaurs, Roman soldiers, Norman invaders, Edwardian gentlemen, and Regency ladies with parasols, etc. all fighting for the space in a giant time-warp.
