I finished Gotrek & Felix's 3rd Omnibus over the weekend, from the Black Library.
I gotta say, I really enjoy the fact that Nathan Long has taken over. William King's stories have been very entertaining thus far, but I find his writing style very very bland. Nathan Long took a series that already had a bland-ish premise (basically Gotrek runs around, and kills the biggest and baddest things in the world in order to redeem some dishonor in his past), and breathed some fresh life into it. I have to say I'm quite excited for the next books, whenever I get to them.
I'm starting Fallen Angels by Mike Lee, book 11 in the Horus Heresy series. It covers the fall of the Dark Angels on Caliban during the Heresy. I'm sure it'll be fantastic as I've yet to be disappointed by any of the series thus far.
