Dragon Imperative

The new Dragon Host goes operational with a mission for the Terrans. But as their numbers and skills rise, so do the questions. Why did the last Host end? Why are dragon kind so scattered? Are there any more to be found? And most importantly, where did the dragons come from originally? But what gets Bud started on all of these is an even deeper mystery. Why do the Keerah fear the dragons and no-one else? The Host must quest for its own past. But for Bud, it's become the Dragon Imperative.
