The Crown Prince died sixteen years ago. The kingdom never learned the truth. To prevent a civil war that would tear YongHai apart, the late Queen buried the greatest secret in the kingdom. Her surviving child ascended the Phoenix Throne beneath another's name, carrying a lie that has protected the kingdom ever since. Now King Yi Hyun rules with an unshakable hand, feared by enemies, admired by the people, and trusts only two souls: Lady Choi, the woman who raised the young monarch, and Kang Jun Ho, the commander sworn to guard both the King... and the truth. In a palace where every smile conceals ambition and every oath may hide betrayal, one secret has the power to bring down an empire. Some crowns are inherited. This one was built on lies.
