I'm a great fan of the Warcraft universe and play a level 60 Alliance Mage of Stormwind in the online version - World of Warcraft. In this tale, Aaron Rosenberg brings the World of Warcraft universe to life in the telling of the time when the Horde first crosses the Dark Portal and unleases mayhem on the world of Azeroth.
The tale is of the Orc warchief Doomhammer and the assault on my beloved Stormwind; it is the time when the Alliance is formed to meet the Horde challenge. Rosenberg keep faithfully to the background plot and brings all the characters from the World of Warcraft alive. If you play the game (especially if you play a Paladin), you will recognise many of the places (perhaps even been there) and many of the characters. If you don't play the game, you'll be itching to buy a copy.
Overall, a well-crafted fanatasy novel, keeping faithfully to the Warcraft theme and adding much to my overall enjoyment (some say obsession) of the game. If you are thinking about buying this, I would recommend reading the book 'The Rise of the Horde' first as it sets the scene to the Horde's journey through the Dark Portal and The Burning Crusade.
