Overall, I liked this, though I feel a bit guilty saying so. The story is pretty basic, but the art is gorgeous. If only the artist didn't feel the need to put so much unnecessary nudity in it. I mean, the naked/topless captives are a bit in bad taste, but are somewhat justifiable in setting; but why do all of the women in the cult of the sacred flame have nothing on under their open-fronted robes except a loincloth or equivalent? Isn't it cold up their in the clouds in their anachronistic hot-air balloon? Also, I could do without the 70's hair, and the apparent perms most of the women appear to have.
Still, there is something to be said for oil-painting (yes, you can imitate its effects with digital painting, but it is so rarely done). And I enjoyed the biographical and making-of information in the back of this book. The artist does a good job of presenting things realistically, for the most part (the main character really should have something under his armor, both because of the elevation, and because bare metal on skin must be uncomfortable (yes, when the armor is shown in detail it appears to have some sort of built-in padding, but that is both unrealistic, and would provide little protection from pinching from the flexing of the segmented armor)). Also, I laugh at the complete ignorance of geological time that would allow the claim that a small pocket of the world allowed some dinosaurs to survive the ice age (the most recent mere thousands of years ago, versus the millions since the end Cretaceous) that killed the others (I will grant that in the 70's the cause of the extinction of (non-avian) dinosaurs remained a mystery, but the time scale is still completely whack). Compared to that, it hardly seems worth noting that the "dragons" are clearly derived from pterosaurs, which were not, in fact, dinosaurs; but they also didn't have the heads of tuataras, so whatever. And why even have to justify the setting as belonging on Earth? And given that, and having a setting in some remote part of the Himalayas, why are all the characters clearly Euorpean in appearance?
Anyway, it is not a book that I would necessarily seek out (as with so many other things I've read, I stumbled across it working at a library), and I certainly wouldn't pay its retail price for it, but if my library system gets more volumes in the series, I will probably read them to see what happens, and to enjoy the marvelous scenery.
