Two warring kingdoms collide when the Espington War Minister captures the youngest prince of Mien and orchestrates a political marriage to secure his own influence at the enemy's royal court. The arrangement horrifies both the reluctant bride and groom, but sparks outrage among Espington's population—particularly a ruthless revolutionary faction determined to preserve their nation's bloodline purity. Unable to act openly, the conspirators hire an assassin to eliminate the prince before the union can be sealed, setting in motion a tense conflict between duty, survival, and the machinations of those who would weaponize murder for political gain.
