Somebody's got mysterious mail

Everybody's favorite 4,000-year-old succubus, a. k.a. Jezebel, got something mysterious in the mail! What what what could it be?

Jackie Kessler is serializing Book 4 of the fabulous Hell on Earth series, entitled Hell to Pay, and the prologue is up now. OMG, Helles Belles was one of the first urban fantasies I read, and it remains one of my favorite. The whole series rocks. I'm so psyched Miss Prolific is doing this #4 online.

So okay, what is Jezebel's first EVER piece of mail as a flesh-and-blood mortal? What is the deal? Why is it so mysterious?

I'm not telling. Go see for yourself.
