This is book #23 in the Anita Blake series, this is a world where vampires are legal citizens and Anita Blake raises zombies to clear up questions about their wills then puts them back to rest.
I would say its TrueBlood mixed with Bitten mixed with 50 shades of Grey.
Though it doesn’t get too kinky until book 4 or 5. And it was around before any of those series.
I really enjoy this series for a fun read. Definitely don’t start with this book though, its almost all sex and no story line. Start from the begining and get to know the charaters and the world they live in.
