Underlord (Cradle, 6)

The sixth volume in the New York Times best-selling Cradle series!
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.
To temper and test them, the Akura clan throws all the elites of the Blackflame Empire into a lush training ground. There, training will be much faster and more rewarding.
Lindon and his team are only too eager to get everything they can out of this opportunity, even when doing so means making new enemies.
The only winners will be those who reach Underlord.
Series Description
The Cradle series is a completed 12 volume series now being published in trade paperback and trade hardcover for the first time. It is the best-selling example of the Progression Fantasy subgenre, which includes works of fantasy where the primary plot revolves around a character growing more powerful in their use of magic.
Cradle is high-stakes, fast-paced, and action-focused, with minimal time dedicated to world-building, and as such the books are lean and focused. The series is often compared to anime, with fans emphasizing the story’s specialty of loud and colorful super-powered battles along with lots of humor.
