When a marriage is arranged to bring peace among two feuding kingdoms, the princess betrothed is suddenly found dead; seemingly murdered within the walls of her own palace. With no clue as to who had killed her, the king suspects his enemy and almost declares war on them himself to avenge his daughter. However, the kings adviser has a solution. The kingdom had never been introduced to the Princess, let alone the enemy, since she had been raised in seclusion; so the strategy was born when one specific lady was present on the night of deliberation. Nesrin Langston, daughter of the captain of the royal guard, is chosen that night to take on the princess's identity and marry the enemy prince in her place, in order to maintain peace until the killer can be found and justice can be served. Can she endure a loveless marriage with a ruthless warlord for the sake of avenging the life of her best friend? Or will she crumble under the pressure and let everyone down?
