From the book jacket:
When Dorina Basarab, half human, half vampire, assassin-for-hire, hits New Orleans, she thinks it’s for a typical job: take out a mad master vamp before he can wreak havoc on the city. But when the elusive master suddenly shows up at her hotel, things get complicated, especially when Dory realizes that the murder he has in mind is his own! And that the Big Easy is about to get a whole lot harder.
