Dirty Thirty

There was a cliffhanger! I adore Janet Evanovich's series about Stephanie Plum. I look forward to each new book. The books are very easy reading, and just fun.
Mostly, it's the same thing - Stephanie's car and apartment get bombed and she likes Morelli and Ranger. She goes to funerals with crazy Grandma Mazur and bounty-hunting with ex-hooker Lula.
But this time, I was left without an ending. Oh no - when is #31 going to be published? I can't wait!
