I read this one because my stepbrother loaned it to me with his recommendation (albeit a mild one). I read the whole thing, just because, and remembered what it was like to read books aimed at teenage male gamers. I used to read plenty of those, back in the day. I didn't like all that many of them then, either, but I read them anyway, because I wanted to know the lore.
"Day of the Dragon" was good enough to not just stop reading part way through. That said, if the book is at all a commentary on the target audience, it's not a very flattering one.
For one, the characters were fairly flat. They spoke with some differences, but the way they thought didn't appear to be very deep. In fact, with some exception to the male lead, most of the male characters bent over backwards just to do whatever they could to be with/appease the very attractive elven female. Fortunately, Knaak doesn't quite rub the readers' faces in just how beautiful she is, the way I've seen some authors, so I appreciated that.
The prose was good enough, but I had to blush to realise that I'VE used so many of the little "tension-building gimmicks" that Knaak uses, namely trying to insert dramatic pauses into the narration. Stuff like, "The sword came rushing at him--
--only to be deflected at the last moment by a spell."
That's not a direct quote (I'm not trying to insert spoilers), but I think it's a good enough illustration. Either way, I suppose it works well enough for the target audience. My problem was that gimmicks like that appear rather frequently through the entire book.
All in all, it was just standard, male teen gamer fare. Simplistic plot, contrived action thrown in seemingly for the sake of it, a mild romance (thankfully, Knaak kept it very clean), complete with the obligatory "hot chick," and everything works out for the good guys (usually at the last, possible moment) no matter how bad things get.
There's really not much else to say, so I'll stop there.
