Try "Best served cold" by Joe Abercrombie. Followed by The Heroes. And to avoid minor spoilers, read the First Law trilogy first. All good books are great, The heroes is probably the best!
Thanks, it looks more like fantasy than fiction - I always liked that Count is embeded is real historic events despite me being fantasy fan and almost never reading historic fiction. But somehow in Counts case it seems essential (and that's way anime adaptation was my least favorite).
