Falling Sky [EPUB ebook] 

Ben Gold lives in dangerous times. Two generations ago, a virulent disease turned the population of most of North America into little more than beasts called Ferals. Some of those who survived took to the air, scratching out a living on airships and dirigibles soaring over the dangerous ground. Ben, a lone wolf, has reluctantly agreed to use his skills and his airship to help an idealist scientist, Miranda, on her search for a cure. Protecting her from Ferals is dangerous enough but when power-mad raiders run rampant, Ben finds himself in the most dangerous place of all—the ground. Ben’s journey leads him to Gastown, a city in the air recently conquered by belligerent and expansionist pirates. Old friends and new enemies are drawn into a struggle that quickly becomes a fight for the fate of the world. Ben must decide to focus on his own survival or risk it all on a desperate chance for a better future. From the Trade Paperback edition.
