For centuries, two kingdoms have waged endless war. The Kingdom of Suncrest worships light, honor, and order. The Shadow Kingdom embraces darkness, power, and survival. Neither side remembers how the war began. Commander Aiden Solis, the most respected warrior of Suncrest, is captured after a mysterious battle beneath a bleeding crimson moon. His captor is Prince Lucien Veyne—the feared heir of the Shadow Kingdom, known across the continent as the Shadow Prince. But beneath Blackthorn Fortress lies a secret older than either kingdom. An ancient prison known as The Hollow. A prison built to contain a forgotten god. When mysterious whispers begin calling both Aiden and Lucien by name, they discover they are connected to a prophecy buried for thousands of years. A prophecy capable of ending the world. As ancient powers awaken and a secret organization known as the Crimson Order manipulates events from the shadows, two enemies must decide whether they will destroy each other... Or save the world together.
