Nadia, a lowborn thief, disguises herself as a man and climbs a thousand-meter-high Sky City with her bare hands to save her younger sister, who has been chosen for “Ascension.” But she soon uncovers the horrifying truth: Ascension is nothing more than a ritual sacrifice, while the city’s ruler is a living power source who has been nailed to the Gods’ Engine for three hundred years.
