The Duelist 4 (The Duelist, #4)

Alex has once again increased his Duelist rank and the size of his holdings and estates.
He’s also become quite enamored with one of the Asher Lord’s mage sisters, but more and more mysteries and questions keep popping up in the world of Aventoll.
Alex will have to keep his wits about him to stay one step ahead of his enemies, and he might even have to leave Nata Isle to find the answers he seeks.
