The Fall of the Sky Lords

Shangri-La is a protected haven built by the enigmatic Eloi, (genetically-enhanced humans of indeterminate sex), and is now the Antarctic underwater prison of Jan Dorvin, once Sky Lord Captain, sometime dictator of the depleted Earth of the Gene Wars, and her maimed lover, Robin.
Far above them, the struggle against the mighty airships an their commanders continues, as Ashley, a rogue computer personality, once again joins forces with the Machiavellian trickster, Milo Haze, against the remaining rebellious survivors of humanity.
Meanwhile, on Belvedere, a religious commune set in deep space, contact is made with Earth for the first time in years and an unexpected counter is thrown into the game. Milo Haze, Mark Two, is about to enter the equation.
