Fool's Gold — Jaye Wells

In the 1970s, Sabina Kane was a rookie assassin looking for first big kill. But when the day finally comes to prove her skills to the Dominae, she finds herself shadowing Slade Corbin, a more experienced assassin with a huge chip on his shoulder. Together, they must track down a blackmailer who's threatening to expose the existence of vampires to the world. Will Sabina and Slade be able to find the blackmailer in time, and, more important, will they be able to get through the mission without killing each other?
