The Deluge Drivers
Alan Dean Foster
 After resigning himself to perhaps being trapped on Tran-Ky-Ky for the rest of his life, Ethan Fortune learns that scientists at the outpost of Brass Monkey have detected a steady warming in the planet’s atmosphere. This has caused something not seen in generations on the planet: open water on the ice oceans of Tran-Ky-Ky. Taking the giant icerigger Slanderscree with a crew of Tran to investigate, Fortune learns that the warming of the oceans isn’t an accidental or natural event.
