Night Huntress series #2: One Foot in the Grave by Jeaniene Frost
The story just keeps getting better and better. In this episode, Cat combines forces with a special ops group of a government agency and Bones tags along for the fun. But the fun turns out to be Bones sire.
I have book 3 in this series and have read the first few pages. So far, it sounds like it will be as good as the other two.
