This is a book that suffers immensely from false advertising. From its cover and the name "Ancient BLOOD", you'd think it was about the blood sucking fiends, the Strigoi, and it's even included in the Vampire Counts omnibus, leading you to believe it'd be about, you know, vampires. But in reality, it's mainly about the Strigany, Warhammer's equivalent of gypsies(Romani if you want to be politically correct). The Strigoi are there, but as sort of an afterthought.
The novel follows a band of strigany as they defend themselves from the onslaught of persecution by greedy elector counts and bloodthirsty mercenaries. This premise, though not pivotal to the lore, is interesting in and of itself; characters such as Chera who struggles with her own ugliness and Brock who is torn by anxiety over the fate of his people provide neat subplots to follow and people to root for.
By the third chapter though, I, like most people probably, was asking myself, "Where the bloody hell are the vampires?" They're there, but they only appear in an unnecessary subplot involving the aforementioned elector counts that goes nowhere.
That's the main issue with this book, in my opinion. It has good writing, good characters, the Strigany are interesting, but the main premise feels like it's building up to something that never occurs. There's a major conflict that doesn't go anywhere, the Strigany make as if to migrate but we never see it happen, the Strigoi, Ushoran, makes plans to reunite with his people but never does; it feels very much like an incomplete story.
