Maeve, the 10th son of the Western Mountains Bandit King, ran away from home to escape marrying his sister since he's adopted. Little did he know that he is just jumping from the frying pan and into the fire when he disguised as a soldier for a neighboring country who is at war. He lost the battle and became a prisoner of war. Maeve's luck is running so low that his capturer is using him as a bargain for easy passage through the mountains his father controls that spilt the two warring nations.
