Death can take on many guises: owl, eagle, groundling, human, plague, storm, and now, Crow. Kyp and his bedraggled band have come through so much, but now they face a new enemy: their own kind. They are being hunted down, methodically and relentlessly. Kuper has drawn hundreds of thousands with his vengeful dogma. They call themselves the Collection, and they are very, very angry.

Kyp's wits and his extraordinary flying skills have never been more tested. He faces a storm of epic proportions, and the fate of each and every Crow hangs in the balance. There is nowhere to hide. The Collection is coming.
