Zombie's Bite (Dorina Basarab #0.1)

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 vampire before he can wreak havoc on the city. But when the elusive master suddenly shows up at her hotel room, things get complicated, especially when Dorina realizes that the murder he has in mind is his own! Now she has a dead master on her hands, a vampire family looking for revenge, and a limited amount of time to figure out what's going on before a shadowy killer kills again. Looks like the Big Easy is about to get a whole lot harder.
