Query: The final book (or is it?)

The title would make you think that the King's son became the master of dragons, but I didn't see it that way. To me, Draconas became the master of dragons, because he outsmarted all of them. Again, not a 5 in my book, I'm stingy with those, but a good series and I would like to see more of Vengeance and his siblings.
