Courage of Falcons

From the front flap of the Gollancz HB: "Kait Galweigh, her Sabir lover Ry and his cousin Ian have captured the Mirror of Souls, an artifact which can confer immortality, but only at huge cost to the innocents whose souls are used to feed it. Thought the Mirror calls to Kait - she had hoped to use its magical powers to restore to life her slaughtered Family - she knows its evil is too great and that it must be destroyed. But the only way to do that, and to ensure that Crispin Sabir doesn't get his hands on the Mirror, is if Kait becomes a Falcon like her uncle, one of the covert group under the aegis of the god Vodor Imrish. And that decision binds her more surely than any iron chains. While Kait and her friends are battling the ages old evil of the Mirror, her cousin Danya, raped and Scarred by Crispin, is being groomed for godhead by the Dragon Luercas, who now inhabits the body of her dead son. Impersonating Ki Ika, the Summer Goddess, and her son Iksahsha, the Chosen One, Danya and Luercas are gathering together a mighty army of the Scarred, ready to invade and conquer the Rich Lands. The destruction of the Mirror will avert a great disaster... but for Kait and her friends, the nightmare is only just beginning."
