All the Times of legends books are good, Nagash, Heldhammer and Melekith. They explains a lot and are really worth reading.
Mark of Chaos was good to your following a bunch of guys and in the end all the story's get together really nice.
Blood for the Blood God was well.... alright I guess... If you really like chaos you might like it....
Which Hunter series was really good, recommended
The Vampire Genive series is really good but a bit confusing you lose track of the time it plays out in. But I guess that's a side effect of the main character being a vampire. Haven't finish't it yet its on ice at the moment... Gonna pick it up some day....
Malus Darkblade series are.... well... AWESOME!
This are the ones I strongest recall reading, Got tons of WH and WH 40k books... Mostly WH 40k usually find them more a peeling. Though Malus Darkblade series is probably one of the best one I have read
