Led by the exiled Turn, the Crow city of Lune has fallen to the invading force of Ravens. But the evil Moravici have not yet been defeated, and as the difficulties of controlling an occupied city intensify, the Moravici launch a direct attack on Sol itself, violating the sacred process of death and raising corpses to obscene life – corpses with a taste for living flesh. Badly injured in the battle for Lune, Turn struggles to hold onto her sense of purpose. But when she displays a new and potentially dangerous power, she is driven to embark on a dangerous journey for the Rook city of Calvaria, where the truth behind the rising of the Moravici may ultimately lie. As ultimate war between the three tribes looms on the horizon, Turn and her friends must fight alone to save them – and the twin worlds of Sol and Nicht – from certain destruction. And what’s at stake may not be only those things, but the fabric of reality itself.
