Lion's Quest: Ultimate (Book 6)

The demon dragons have awoken, and they have only one objective:
Consume all the magic on Ohlavar.
Leo and his band of misfit adventurers are all that stand between the countless number of demons and the innocent inhabitants of this very real fantasy world. It will be the ultimate challenge of his life, against impossible odds, with only a few days to plan.
But Leo is the best there ever was, and the best there ever will be.
The Champion never loses.
