The most dangerous enemy they will face in battle is the one intent on revenge. 670 CE. Yuvaraja Ugrasimha has really only known peace. As the crown prince to a small but extremely wealthy kingdom nestled in the crossroads of the Silk Road, the eighteen-year-old and his younger brother grow up untouched by surrounding wars. But when tasked to destroy a band of Arab raiders preying on caravans, he barely survives the fierce fight with the wicked leader before making a drastic mistake… letting the vengeful man escape. As the wounded raider rebuilds his strength and power in nearby Persia, Ugrasimha takes command of his kingdom's defenses to protect their borders against rising threats. And when their vindictive foe marches a mighty army towards the capital, the young prince and his brother struggle to overcome surprise attacks, cruel betrayal, and the risk of defeat. With an invading force bearing down on them, will Ugrasimha be the shield his kingdom needs, or the crack in the wall that lets it fall?
