The Sky Lords trilogy – John Brosnan epub

The Sky Lords
Centuries in the future, after the world has been devasted by the Gene Wars, the scattered remnants of humanity struggle against both the spreading biological blight on the ground and the great airships that dominate the skies. Controlled by feudal warlords, these mile-long dirigibles patrol their territories, exacting tribute from the ground communities.

War of The Sky Lords
Former slave Jan Dorvin now commands her own Sky Angel, one of the gigantic airships used by the powerful Sky Lords to dominate the landbound populations of a devastated Earth. Determined to free the surface peoples, Jan is besieged by enemies within, as her ship's artificial intelligences turn against her, and without, as the Sky Lords join forces for a mass attack. Embellishing a familiar sf theme of primitive civilizations relearning vanished technologies, Brosnan creates a fast-moving sf adventure.

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 and 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.
