What to read after Past Redemption?

If you passed Daphne Urban on the streets of New York, you’d see a sleek young brunette dressed to kill. You’d never know she was a vampire. But the government knows. Their ultimatum - Spy for the United States, or be terminated. And after all these centuries, Daphne is not ready to call it quits. The word is out on Susto. It’s a new recreational drug that intensifies sex, it’s spreading like wildfire - and it’s lethal. Team Darkwing’s mission - Track the drug back to its origin. Immersing themselves in New York City’s nightlife, they soon discover ties between Susto’s billions in revenue and the country’s most powerful political dynasty. To infiltrate the family, Daphne flirts with its weakest link, handsome party boy St. Julien Fitzmaurice, whom she’d love to casually sink her teeth into. But even as their dalliance leads her deeper into the case, Daphne can’t stop thinking about Darius, the darkly sexy human she claimed with a passionate bite. He’s the bad boy she knows she should - she must - forget, because if she doesn’t, she’ll be risking not only the mission, but her own heart.
