Nopalgarth Three Complete Novels

"Here's a special treat for Jack Vance's legion of readers! Three complete novels, long unavailable, back in print in one book! ; Nopalgarth: The nopal came from outer space to take over the brains of humanity--and it took the thinking of another set of alien monsters to prepare a mental Armageddon! ; Son of the Tree: The might tree of life ruled a world, dominated the sky, and held the power of life and death over millions of worshippers--until Joe Smith came along. ; The Houses of Iszm: The best homes in the universe were grown from seeds genetically programmed on the planet Iszm. The theft of just one such seed would be a prize worth billions!"--Pg. [4] of cover.
