Sky Pirates of Callisto
Lin Carter
 Jonathan Dark (Jandar), earthman mysteriously transported to the Jovian moon of Callisto (or Thanator), has in concert with the native Ku Thad succeeded in freeing the city of Shondakar from the occupying Black Legion and the opportunistic Zandaharian Sky Pirates. The only fly in the ointment is that Shondakar's rightful ruler, the princess Darloona, has been abducted by the fleeing Prince Thuton of Zandahar. To free her Jandar adopts the wild plan of taking one of the Sky Pirates' own captured airships to raid the enemy city. A Zandaharian prisoner brought along to help operate the craft treacherously scuttles the scheme by throwing Jandar overboard and sabotaging the airship. Plopped into the Corund Laj, Thanator's greater sea, Jandar finds himself close enough to land to swim to safety, only to be enslaved by the mercantile Perushtar who rule its waves. Ironically, this results in him reaching his destination after all, as he is sold to the Zandaharians as gladitorial fodder. He has his hands full simultaneously surviving as a gladiator, hiding his identity as the Sky Pirates' arch enemy, and stirring up a revolt among his fellow slaves. As the revolution ignites and he if found out, his allies' airship, now repaired, swoops in to administer the coup de grace. Zandahar is destroyed and the menace of the Sky Pirates ended by the explosion of the pocket of "lifting gas" over which the city is built and on which its air power is based. Best of all, Jandar at last finds favor with the rescued Darloona, whose relationship with him amid the perils and reverses of the previous books has been decidedly rocky.
