Book V in World of Tiers. The lavalite world is a world of slow yet constant change. Here, mountains rise from plains or sink into rifts; new oceans form as vast hollows collapse and seas rush in. There is only one escape from this world - the gateway to other universes is in the palace of the Lord Urthona. Paul Janus Finnegan - also known as Kickaha - must reach it if he is to survive. And he must do so despite Urthona, Red Orc, the hired thug McKay, flesh-eating vegetation that's on the move and planetary pseudopods. Cover art by Boris Vallejo.
