This book was fun enough, and it delivered on its promise of Vampire Brides (VBs). Unfortunately, I found its tone confused; firstly, the presentation of the VBs and, secondly, the overall tone of the book.
The VBs were definitely the protagonists of the book - aside from a few interludes from the perspectives of various vampire hunters / victims. However, the story alternated between presenting them as 'heroes' (or at least sympathetic figures) and cold-blooded murder monsters (with Jonathan Harker and Helsing as being the real heroes). It's a tough job trying to get readers to invest in unsympathetic murderers, and I don't think this book succeeded in doing it.
The book seemed to struggle to decide if it was horror-lite (e.g. Van Helsing, the film), proper gory, limb-tearing horror, or cosmic horror. I enjoy all three to varying extents, but the marriage of them together felt off in this instance.
The writing is solid. There were very few typos or grammatical errors. The action scenes were good. It was modern in style, and there were some enjoyable moments of wink-wink snark; although, other moments fell flat or were just unbelievable from that time in history. Similarly, the setting of Eastern and Central Europe felt like window-dressing at best.
Final comment: the greatest annoyance in this book was the number of times Senka said she wanted to "bite him" (25), "bite them" (15), "bite her" (2), "bite it" (2), or "bite" in general (104). Obviously, there's going to be biting in a vampire book, but this seems excessive. Why not try some synonyms about sucking blood?
