The sequel to Midnight, Water City follows a detective from the depths of earth's oceans to the moon as he unravels a cosmic conspiracy that threatens to destroy the remnants of human life.

Year 2150: Eight years after the murder of Akira Kimura, Water City's renowned scientist and anointed "God," the nameless antihero who tracked down Akira's killer is no longer a detective, but a stay-at-home dad. While his wife climbs the corporate ladder of the city's police department, he raises their now nine-year-old daughter and occasionally takes the odd job as a bounty hunter.

His domestic bliss is threatened when Ascalon's Scar--the mark left by Akira's destruction of Sessho-seki, the asteroid that nearly wiped out life on Earth--vanishes from the sky and a familiar face thought dead returns from the ocean depths to exact revenge on humanity. On a journey to the moon and back, Water City's antihero will risk everything, including his family, to save the last of the human race--even if it means unraveling the dark conspiracy at the heart of their world.
