One of the Warcraft novels I've actively been looking forward to is Arthas, Rise of the Lich King. It's set to be released to the world on April 21, 2009 but BlizzPlanet.com has gotten its hands on a few bound galleys of the book early. Some of them are being given away, but he's also reading one on his own and has gifted us with a quick review.
The review makes the book sound incredible, though perhaps a bit too cluttered. The novel is roughly 300 pages in length (I believe) and the first 100 pages covers his childhood from the arrival of the Stormwind refugees in Lordaeron to the beginning of Warcraft III. That covers about fourteen years, and that's potentially a lot of territory to cover!
