I'd advise you to read this excellent series in order.
This is the 3rd in the series and it just gets better. This is urban fantasy, with a likeable heroine, who isn't too tough or too hard or even too damaged. She's funny, kind, sexy and kick-ass! But, and this is a big thing for me in urban fantasy, there aren't the long drawn out sex scenes that you get in some fantasy books, there's romance and the odd sex scene, but they aren't all consuming, and they are well written and fit with the story. This is the story first, building in excellent characters throughout.
This book starts with the were population 'coming out' to the World. As security advisor to the big vamp boss, it's Jane's job to make sure all goes well. Obviously it doesn't - cumulating in lots of fights, Jane's new boyfriend going missing, and Jane working with the gorgeous Bruiser, and the fabulous ex-Marines led by Derek Lee to help fix all the problems.
Vampires, Were's and Witches (oh my!) and the excellent Jane Yellowrock, a skinwalker.
I read all three books in 2 days, and I loved them. If you like the Mercy Thompson series by Patricia Briggs, or the Toby Daye series by Seanan Maguire, then I hope you'll love this series as well.
