I real this book a few weeks ago, and hope that a few others have by now as well so we can get a discussion going
I quite enjoyed the book, but the think that I liked the best was that it finally started to fill a hole in the Empire that has been there since the storm of Chaos- namely, a major Imperial province not having an Elector Count. Finally they seek to redress this, which is nice, even if not fully resolved by the end.
I can't quite work out the timeline of the book though, the Empire seems a fairly cheerful place, but there's talk of war in the north (I suppose there always is...), while the famous Empire heroes are active in the forests in the Empire, instead of leading great charges against the northlanders (But the Wizards are all up there?). Going by the blurb for the sequel Volkmar will star too, so it's either actually quite a while ago, or well after the Storm of Chaos.
Or, another possibility... Storm of Chaos officially ignored by Black Library as never having happened
As for the characters, a little one-dimensional, but that's the usual. Ludwig was equally far too proud and far too weak a man to be the title character, but I guess half the fun is seeing his fall from grace and the poor decisions he makes. And as usual there's major Chaos cults everywhere, I swear half the Empire must already be Chaos worshippers...
