Majadan has fallen. The Empire of the Sea-Elves is next.

Moth Blackwater is the last of her kind, a shapeshifting nomad – part human, part raven – whose tribe once wandered Majadan's skies. Now that the Wight Lords have murdered her family, and the city of Majadan itself has been conquered, Moth is on the run half a world away in an ancient archipelago of sea-faring elves.

The Empress Tatiana, once a prisoner of the Wights, has ruled her island empire for two thousand years. The power of her navy has brought peace to the world, but never has the Empress turned her strength against the Wight Lords' evil. As their oncoming war threatens all of civilization, there are some who believe she won't lift a hand to stop them.

During a desperate gamble to survive, Moth stumbles on the secret at the heart of Tatiana's reign: a hidden connection between the Empress and the Wights that endangers all the nations of the world. As Tatiana's admirals plot to retake Majadan by force, Moth will join a conspiracy to dethrone the Empress herself.

At first, Moth was searching for nothing but a home. In that search, she was swept up in the fight to save her people. But when all sides turn against her, when every friend becomes a foe, when the threat of destruction hangs over all she holds dear, can one lost girl stand against an Immortal?

No matter the odds, Moth will have to try.
