Callisto — Lin Carter

THE CLASSIC FANTASY SERIES FROM THE CO-AUTHOR OF CONAN THE BARBARIAN! At the height of the Vietnam War, Jon Dark is a helicopter pilot for the International Red Cross, flying numerous rescue missions...until the day his helicopter crashes in the Cambodian jungles. Cut off from American troops, he searches for a way out, only to find a lost city -- and the gateway to another world. Stepping through the portal, he arrives on Callisto -- a savage, hostile world terrorized by insect-men and the infamous Sky Pirates of Zanadar. It is a world of black and crimson jungles where Jon Dark -- now known as Jandar -- finds not only chilling dangers awaiting him, but also the love of a beautiful princess.
