FYI- I registered here just to post the below.
I will preface my review with a couple of points: I have been a pretty big booster for Dragon Age for a long time. I am a bit, I will admit, of a bioware fanboy. I also have read and own a fair amount of genre fluff/video game/board game tie-in novels. I cut my teeth on the old Weiss&Hickman Dragonlance novels. I have some of the worst fluff out there (see Halo novels, for example) and some of the best (a lot of the Warhammer 40k stuff, probably because it isn't shackled to any specific pr platform -that is, selling a specific video game-, are pretty ok). I'm not sure if it's fair to compare Gaider to a non-genre novelists or even someone like George RR Martin or the like so I'm going to try and avoid doing that as a main point of the review.
SO: If you are buying this for fluff alone, then you will be satisfied. The book is great pr for the game from a fluff perspective. It's horrid pr if you consider that its the product of one of the people behind a lot of the writing, story and world crafting. It is ridden with stylistic, literary and grammatical cliches. There are glaring grammatical errors. I am a pedant, especially when it comes to grammar and I definitely "ragequit" reading this quite a few times. To put it another way, had I not known this was a video game pr novel I would have a) probably not been able to finish it (and I almost always finish books), b) become seriously wary of reading anything put out by that publisher before reading a bit of it in the store and c) think that Mr. Gaider was 14 years old, or new to writing anything (maybe even new to the English language). I know that sounds harsh, but when you come to something, wanting to like it, hoping its great, the jolt and let down that follows when it not only fails to meet your expectations but, instead, seems determined to frustrate you at every turn, then it's hard not to be a bit emotional. Honestly, at times it was like this book wanted me to hate it.
All that said, I am picky and have what are probably abnormally high standards for even genre pr tie-ins. You may love this book. I think coming to it with your expectations adjusted (this ain't Gene Wolfe, much less Glenn Cook, much less something like Gaunt's Ghost.) is a great idea. EDIT- and just to temper the harshness above a bit more: David Gaider is not a novelist. Writing a book and making a good video game are two very different things. I liked the games he has worked on so far. I do a good job around the office, but I am a pretty crappy at playing the recorder. If my boss came to me tomorrow and decided the best way to "sell" the firm was to have me play my recorder, then I'd do my best, but... well... I am a crappy recorder player.
The other problem, I think, is that tie-in books are in a sort of nebulous area. They obviously can't be too artsy and they are almost certainly combed over (and over) by some pr guy who cares a lot less about plot pacing than about how well it hits each of the bullet points in his press release.
