As an avid World of Warcraft player, I was rather looking to picking up Richard Knaak's trilogy, mainly because I was interested in all the lore and background, but also because I heard quite a few positive reviews about his Dragonlance novels.
Unfortunately, while the trilogy fully satisfied my craving for the former, it was an utter disappointed in terms of the latter. Knaak's writing isn't just horrible - it's downright atrocious, to the point where you honestly start to wonder whether the book was dumbed down to suit a more juvenile audience or whether it really takes that little to become a NYT bestselling author. Character exposition is, well, exposed - there are absolutely no subtleties and Knaak has no qualms about reaching into his characters' heads and presenting their most complex motivations with just a few lines. His description of Broxigar's survivor guilt was so bland and in-your-face that it made be cringe. At no point does Knaak ever leave you guessing about his characters or asks you to think for himself - explanations for even the most complex emotions are presented in an oversimplified, overexposed manner that literally leaves nothing to imagination.
Bottom line is, if you like World of Warcraft and want to familiarize yourself with its lore, then by all means read this book. If, however, you just finished reading the Wheel of Time or Song of Ice and Fire (I'm not even mentioning LOTR), please, do yourself a favor and give it a miss. Your literary taste will thank you for it.
Or, to put it differently, if you thought Terry Goodkind's earlier SoT books were the masterpiece of literary talent, then you will most likely enjoy Knaak's WoW books.
