There will certainly be sequels, but the story stands on its own. No new Dragonlords have been born since Linden, however, so he seems doomed to be the last of his kind.
Linden also has an intelligent horse.
The horse isn't particularly relevant to the story, but all wish-fulfillment fantasies have to have intelligent horses. It's in the rules somewhere. Upon the death of the queen of Cassori, Linden is sent with two other Dragonlords to decide who will become regent for the young prince. Cassori's bickering nobility fawn over them in public, but not everyone is happy about letting were-dragons sit in judgement over true humans, and this is a golden opportunity to rid the world of a few Dragonlords. The good guys all just love one another to pieces, and their dialogue is sometimes syrupy.
