Firstly, I'd like to make it absolutely clear that I don't regret buying this book. What comes next may well seem quite negative, so I want to make that point perfectly clear. The story is not great, but you do get to spend a bit of time reading a fairly interesting story, with many interesting concepts along the way. That's a fair enough return for your money, isn't it?
The first two books in the Dragon Master trilogy have some weak points, but they are quite readable. Some of the characters are a bit flat - mainly the secondary characters, but even some of the main protagonists seem underdeveloped - and that's not really good enough. But the books are helped by some good solid plotlines along the way, though not all the way.
The last book in the trilogy however, just doesn't cut it. It's simply too weak. The story is messy and the characters become even flatter than in the first two books. In a way, this omnibus isn't really a trilogy. It's more like a duology with a third book about the same group of characters stuck on in the back.
Chris Bunch tends to base his fantasy wars on real wars. In the Seer-trilogy he used the Napoleonic Wars and in Dragon Master he uses World War One. Sometimes it works and sometimes it doesn't. When Bunch describes the gruelling, attritional battles with thousands of dead lying in piles on the huge, devastated battlefields, you really feel for the people in the book and you shake your head in sorrow at the harshness of the world; both the fictional and the real. When you read about the dragons in battle, you tend to shake you head again, though not really for the same reasons as before.
The dragons, you see, don't really work all that well. The action-part of the aerial battles is OK, but conceptually there is a problem. The dragons and dragon-riders are described much like the fighters and fighter-pilots of WW1. On the face of it, this seems like a good idea, but there are problems. The wild semi-intelligent dragons fight fiercely among each-other when they aren't ridden by a human, but once trained and flown, their behaviour changes radically. So radically, that when a dragon-rider is killed, his dragon either panics and flies away from the battle or looses it completely and crashes alongside the dead rider. It doesn't really fit together.
And that brings me to my main complaint about this book; a lack of consistency.
At times, the writing sucks you in and slowly begins to absorb you into this world, but then, without any preamble, it somehow goes wrong and you get spat back out again. It could happen at any time and in different ways, maybe the dragons would act without any degree of consistency or the bad guy would suddenly be an alright-kinda-guy. For me, it was often when something magical happened. I'm not really a big fan of the way Chris Bunch uses magic in his stories. I didn't like it in the Seer-trilogy and I didn't like it in this book either. The silly rhyming doesn't help, but mainly it's (again) the lack of consistency that does it. Magic is hard to learn and takes a great toll on the person using it, but the army still manages to have a good supply of magically preserved food, like the canned food in WW1. Consistency?
I won't tell you not to buy this book - you could spend your money on worse books - but I won't recommend it either.
