Margaret Owen The Faithless Hawk

As the new chieftain of the Crows, Fie knows better than to expect a royal to keep his word. Still she's hopeful that Prince Jasimir will fulfill his oath to protect her fellow Crows. But then black smoke fills the sky, signaling the death of King Surimir and the beginning of Queen Rhusana's ruthless bid for the throne. Queen Rhusana wins popular support by waging a brutal campaign against the Crows, blaming them for the poisonous plague that wracks the nation. A desperate Fie clings onto a prophecy that a long-forgotten god will return and provide a cure to the plague. Fie must team up with old friends-and an old flame-to track down a dead god and save her people.
