Diamonds of Ice

Sorcerer Fabrice Germain lost his Talent when he was assaulted, but he still has his job. Relocating to London seems like the answer, and then he meets Gemma, who works for his rival. She’s a vampire. That’s two reasons to avoid her, but Fabrice and Gemma still end up scorching the sheets one Saturday night.
Then the world goes to hell. Fabrice ends a weekend of passion and tragedy as a converted Talent - a vampire now, like Gemma. One who has sworn to avenge two murders, and is back as an agent with Department 57. After that, he’s happy to die.
Except there’s Gemma. Fabrice really wants Gemma.
Gemma doesn’t want Fabrice to surrender to the blood phobia that threatens to take his life. She wants him for longer than a night--in fact she thinks she might never get enough of him. When they’ve caught the murderers, what is there to stop him starving to death? Only her.
