Illidan: World of Warcraft
Novels that take place in role-playing games are a big business and can greatly expand the universe. Just look at the Warhammer series, the novels are incredibly popular and span both fantasy and science fiction. Now it seems World of Warcraft wants to get into the game and publish books that expand its universe. Even though one game is board based and the other is computer based. Honestly as an early effort this falls a bit flat, and William King is well known for his Warhammer books so this effort is surprising. We follow Illidan who has been locked up for thousands of years after betraying the people he was ruling, but now the darkness returns and Illidan is the only one that can stop it. He must gather together a fearsome army, but not everyone trusts him.
This feels like a weak Warhammer book and I will forgive people if they have a hard time telling the difference, the names are similar to what can be found in Warhammer books. If Blizzard is looking to differentiate itself from the other universe it could have done better.
