Blood Oath by Christopher Farnsworth

Sharp and ambitious, Zach Barrows is on his way up. But when he gets a call from the White House, it’s not quite the promotion he expected. Zach is to be the new political liaison officer to America’s best kept secret: Nathaniel Cade. The President’s vampire. And Cade is the world’s only hope against a horrifying new terrorist threat advancing from the Middle East. The fight is deadlier than ever, and time is running out . . . Like partners in a mis-matched buddy cop movie, the relationship between Barrows and Cade is at the heart of this novel. Barrows starts the novel blissfully ignorant of the supernatural forces that exist in the world. After an unexpected promotion, the truth is revealed and his world view is completely turned on its head. Initially, Barrows is all cocky attitude and very sure of himself, glad to say that doesn’t last very long. Cade by contrast is aloof, and considers humans to be little more than cattle, exactly what you’d expect from a long lived vampire I suppose. The events this pair go through start to bring about a mutual respect and by the novel’s end there are hints of a bromance…
