By way of a staggering deception, Karou has taken control of the chimaera rebellion and is intent on steering its course away from dead-end vengeance. The future rests on her, if there can even be a future for the chimaera in war-ravaged Eretz. When Jael's brutal seraph army trespasses into the human world, the unthinkable becomes essential, and Karou and Akiva must ally their enemy armies against the threat. It is a twisted version of their long-ago dream, and they begin to hope that it might forge a way forward for their people. And, perhaps, for themselves. Toward a new way of living, and maybe even love. But there are bigger threats than Jael in the offing. A vicious queen is hunting Akiva, and, in the skies of Eretz ... something is happening. Massive stains are spreading like bruises from horizon to horizon; the great winged stormhunters are gathering as if summoned, ceaselessly circling, and a deep sense of wrong pervades the world.
