Deathworld and Deathworld 2 by Harry Harrison

This Halcyon Classics ebook edition contains DEATHWORLD and DEATHWORLD 2 by eminent science fiction writer Harry Harrison. In DEATHWORLD, professional gambler Jason DinAlt accepts an invitation to visit Pyrrus, the most lethal world in the known galaxy. For outsiders, Pyrrus usually means a quick and painful death, but DinAlt is fleeing the crooked casino masters of Cassylia - where he just broke the bank. But DinAlt is not prepared for the hellish Pyrrus, where every living thing seems bent on exterminating mankind. In DEATHWORLD 2 (originally published as THE ETHICAL ENGINEER), Jason DinAlt finds himself on a hostile, barbarian planet where technology and civilization have almost disappeared. Using his skills, DinAlt literally reinvents the wheel in his quest to escape and return to his friends on Pyrrus.
