Infused with folklore magic and history, The Firebird's Vengeance is the stunning conclusion to the Isavalta trilogy, from major new fantasy author Sarah Zettel. You will pay for this, screamed the Firebird. Life and blood and realm I will have from you. Thirty years ago the Empress of Isavalta imprisoned the terrible Firebird in a cage wrought with gold, magic and blood. She succeeded in saving her realm, but at a harsh price: the life of her loyal sorcerer, Avanasy. Now, with the Empress's death, the Firebird has been freed, and its desire for revenge is unquenchable. Avanasy's daughter, Bridget, is warned by the Vixen, a great spirit-power, of the Firebird 's coming attack. But the Vixen also brings other, equally disturbing news: that Anna, the daughter Bridget buried as an infant nine years ago, is in fact still alive. Bridget is torn between her duty to defend her adopted homeland and her desperate longing to find her child. But she is not the only one with an interest in the girl. Bridget is the daughter of two sorcerers, as is Anna herself. Such a child is likely to be possessed of extraordinary powers. Powers that might be harnessed to save an empire -- or to destroy one.
