One thousand years ago, the Elduari conquered the country of Varen in a brutal war. Now, every few generations they subject their one-time enemies to a terrible tradition: bloodthirsty monsters are unleashed across the land, attacking indiscriminately, keeping the population in a perpetual dark age.

For Argo, fear of another Release is something he has always lived with. When his friend is killed by a monster during a routine patrol, Argo suspects that another Release is coming, and sooner than everyone expects. But in a country built on fear, getting answers is dangerous. Elduari spies are hiding behind the most familiar faces, and any hint of disobedience could lead to the death of thousands.

As whispers of dissent circulate, rebellion grows in the villages. Now Argo and his new ally, Ana—the King’s eldest daughter who is also a monster hunter in disguise—must decide whether or not to join the fight. But what if it’s already too late?
