Ryland Grace is the sole survivor on a desperate, last-chance mission—and if he fails, humanity and the earth itself will perish. Except that right now, he doesn’t know that. He can’t even remember his own name, let alone the nature of his assignment or how to complete it. All he knows is that he’s been asleep for a very, very long time. And he’s just been awakened to find himself millions of miles from home, with nothing but two corpses for company. His crewmates dead, his memories fuzzily returning, Ryland realizes that an impossible task now confronts him. Hurtling through space on this tiny ship, it’s up to him to puzzle out an impossible scientific mystery—and conquer an extinction-level threat to our species. And with the clock ticking down and the nearest human being light-years away, he’s got to do it all alone. Or does he?

Emriss Silentborn, Memory of the World. Tiberian Arelius, the fallen Patriarch. Akura Malice, Queen of Shadows. Seshethkunaaz, King of Dragons. Reigan Shen, Emperor of Lions. Luminous Queen Sha Miara. The Eight-Man Empire. Northstrider. The Monarchs, the most powerful sacred artists on Cradle, rule with unquestioned authority. They are mysterious and distant, and catching a glimpse of one is privilege enough for a lifetime. Now, they have all gathered in one place, bringing their heirs and greatest students together for a competition to determine whose successor is the best in the world: The Uncrowned King tournament.

A tournament approaches. All around the world, great clans and sects prepare their disciples to fight against one another in a competition of young Underlords. Even the Blackflame Empire is drawn in, but their youth are not strong enough to compete. Yet.
