In 1908, with world war a dark prophecy on the horizon, an English traveler, Auberon Harwell, enters a far valley in Montenegro -- a spy sent to assess the political situation while posing as a botanist. Drawn into the drama of a young Serb in love with an unattainable woman, Harwell's sense of duty and honor will be severely compromised by his own dangerous desires -- leading him toward a shattering confrontation that will forever change the world he thought he knew.
