Ab Irato (Ab Irato #1)

In a dystopian future of rising sea levels, the rich have access to a rejuvenating vaccine that can allow lifespans of hundreds of years. A young man named Riel arrives in the urban metropolis of Montreal and meets a young woman, Neve, who is allied with rebel insurgents (the 'Bastards of God') fighting the corporate powers that control the city and the vaccine.
