The latest Gotrek and Felix novel gets into some good ol' Greatsword action, as its about the two main characters stuck in a castle with an Imperial Army, but it obviously does not focus on them.
I agree with SOF - the new Black Library Novels do not really immerse the readers well. (of course, GW thinks of the definition of "setting" is "add more skulls"). I have not read Grimblades yet, but I have read Iron Company and Call to arms.
This maybe the history nerd coming out in me, but I cringe everytime they put Empire Swordsman in a Shield Wall... The shields the 7th ed Troopers are more like oversized bucklers, not proper-sized shields. When I hear "Shield Wall" I picture 10th Century Vikings, not 16th Century German swordsman spilling out from between static formation to cut off enemy pike heads and stab bellies... (but hey, its fantasy)
The Gotrek and Felix novels do a wonderful job of providing that "Warhammer" feel to the books. They are always enjoyable.
