An inexplicable ailment was striking down the children of Russia; in less than forty-eight hours, American medical missionary Sarai Curtiss had watched two young patients slip away, and she feared she might have an epidemic on her hands. Yet how could she help anyone in the middle of a violent coup? The new leadership had demanded all foreigners leave the state—on pain of death.Unwilling to leave her clinic, but unable to combat her enemies alone, Sarai had to join forces with an unlikely ally—Roman Novik, the rebel Cobra Captain who broke her heart. Faced with a corrupt government, a brutal military and the truth of their own deepest feelings, it would be a race against time to save the lives on the line—and an entire country at risk.
