The lavalite world is a world of slow but 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 where the very landscape moves. 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 and Red Orc, the hired thug McKay, flesh-eating vegetation on the move, and planetary pseudopods... The book is complete and in VERY GOOD - FINE condition with some overall wear and tanning pages. Great cover by Boris Vallejo! (see pictures)
