Suggestmeabook that is based on vampires but during medieval times

I've started to read this book I found on Amazon kindle, it's called the record keeper (Seraphine's journal) , pretty much vampire stuff, and a vampire hunter, the story looks good so far, I've also been reading the count of Monte cristo and I like the way the words are expressed, the world building system, how their accent is that written so perfectly one can mimic them by simple reading their lines… I want a combination of both, vampire setting with the count of Monte cristo writing…
