American Witch In Paris by Michele Hauf

Taken hostage in Paris…but bound by desire.

Tired of his desk job, Ethan Pierce decides it's time for a more exciting occupation. This straitlaced vampire may be ready for demons and blood magic, but nothing can prepare him for Tuesday Knightsbridge. She's brash, she's bold and she's the sexiest woman he's ever met. She also happens to be a witch…and the key to saving the world.
