A devastating attack. A twisted conspiracy. A fight for the fate of the largest city in the world. Sha Moonsun and her Fox Den of teen thieves scrape out a living on the poorest streets of Razgov-known as The Endless City. But when an inexplicable attack turns their Ward to ruin, they are mysteriously summoned before the powerful Commander of the City Watch. He reveals a secret that suggests that Sha and her colorful band of misfits may have a role to play in preventing the next catastrophe. But to do so, they'll have to join forces with Ezra Vandertu, the only son of one of The Endless City's most prominent families with plenty of his own secrets to hide. Sha, Ezra, and the Den embark on a mission that will take them from the subterranean world of Razgov's infamous Undercity to hidden rebel safehouses to the very halls of power that govern the largest metropolis on the map. Every turn reveals a new glimpse into a massive conspiracy that could mean the end of Razgov, and time is running out to stop the forces bent on bringing the Endless City to its knees. Can Sha and her Foxes overcome the ghosts of their pasts and finally do something worth remembering? Can she really trust the perplexing but charming Vandertu? And can the Fox Den use the skills they've honed to save the only home they've ever known before it's too late?
