The Zenith, The Stronghold, the Forge and the Atom. A tetrarchy of empyrean metropolises that uphold and enforce the laws of the land. Doctrines that ensure that everything from wealth to opportunity to security comes at a cost. A cost that is paid in borrowed time.

With the ever-looming threat of being demoted to the savage and lawless Lowlands that lie below, those who reside on the Sanctuary Cities are constantly walking on eggshells. How many mistakes a person can make until they're served with a demotion always varies, but for Piper McTaggart, it only took one.

With a single error that was falsely attributed to her, the life she had spent years building for herself was now forfeit. Stripped of her rank, her station and her wings, Piper must now survive in a treacherous land unknown to her long enough to discover the truth behind her demotion, and how it connects to an expansive web of intrigue that spans the Sanctuary Cities above, and the Lowlands below.
