Deathworld 2

Description for DEATHWORLD 2 by Harry Harrison:

THE PLANET PYRRUS WAS A LIVING HELL OF UNSPEAKABLE TERRORS---AND JASON DINALT COULDN'T WAIT TO GET BACK TO IT...

Pyrrus is the killer planet.  A World where all life forms have evolved into organic killing machines of murderous precision.  Even the genetically hardened and technologically armed inhabitants have to fight tooth and laser just to survive day to day.

So, who in the galaxy would go to Pyrrus?  Jason dinAlt, professional gambler and intergalactic flim-flam man extraordinaire, that's who.  So far he's managed to survive, sort of.  But when Jason's kidnapped by a political fanatic---only to escape into the clutches of space slavers---he begins to yearn for the good old days on the killer planet.

This is #2 in Deathowrld Trilogy.
