Watch a video Zach Barrows is an ambitious young White House staffer whose career takes an unexpected turn when he's partnered with Nathaniel Cade, a secret agent sworn to protect the President. But Cade is no ordinary civil servant. Bound by a special blood oath, he is a vampire. Cade battles nightmares before they can break into the daylight world of the American dream, enemies far stranger-and far more dangerous-than civilians have ever imagined. Blood Oath is the first in a series of novels featuring Nathaniel Cade-the President's vampire. "Christopher Farnsworth's taut thriller Blood Oath is an irresistible page-turner.... A complex and unnervingly realistic tale in which vampire Nathaniel Cade is far less of a monster than his human colleagues at the CIA and FBI. Dazzlingly clever."—The Washington Post "Blood Oath is exactly how I like my Presidential thrillers. With vampires."—Brad Meltzer, author of The Book of Fate "Blood Oath is the vampire novel that finally gets it right. Christopher Farnsworth has done his homework in places where most writers wouldn't even know to look-and the result is a rollicking tale of the supernatural grounded in some of the true oddities of American history. If Dan Brown wrote a vampire thriller, this would be it."—Mitch Horowitz, author of Occult America "As someone who thinks Stoker's Dracula has never been bettered, and who would happily stick a stake through the heart of most modern vampire fiction, it almost pains me to say how much I enjoyed Blood Oath. Witty, exciting, and compulsively readable, with a central character who seems destined to become a favorite of both skeptics and true blood believers, this may just be the best debut vampire novel in many years." —John Connolly, author of The Lovers
