Two of my friends recommended the Anita Blake series. I just finished the Charlaine Harris vampire series recently, and there are some similarities in the feel between the two. I plan to read the rest of this series, although I think I might take a break from the vampire genre for a little while. So far I think that I like the Charlaine Harris series better, but I will decide later after I have read some more of the Laurell K. Hamilton series. Also, I didn't feel like I gave this book a fair chance as I read it on airplanes and when very tired. I didn't feel like I gave it the attention it deserved at these times (and probably missed out on a lot of details!).
