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.

The ultimate secret. The ultimate agent. Nathaniel Cade returns. For 140 years, Nathaniel Cade has been the President's Vampire, sworn to protect and serve his country. Cade's existence is the most closely guarded of White House a superhuman covert agent who is the last line of defense against nightmare scenarios that ordinary citizens only dream of. When a new outbreak of an ancient evil-one that he has seen before- comes to light, Cade and his human handler, Zach Barrows, must track down its source. To "protect and serve" often means settling old scores and confronting new betrayals . . . as only a centuries-old predator can.

A man stands up in a crowded movie theater. A moment later, everything is burning. When the smoke clears and the bodies are removed, there is no trace of any bomb, or device, or even a matchstick. There's just the corpse of one man, a statue in ash, with an obscene grin still upon his charred skull. Nothing human could have done this. Fortunately, Nathaniel Cade isn't human, either. Turned into a blood-drinking abomination 145 years ago, he is bound by a special blood oath to serve and protect the United States from supernatural threats. Together with his White House handler, Zach Barrows, Cade races to find out who was behind the murders of a dozen innocent people. They have no suspects, no leads, and no explanations. All they have is Cade's vampiric talents and a ticking countdown to the next explosion. Because Cade is certain of one thing: this is only where the fire starts...

The Presidential Campaign Trail, 2012: A political operative and a volunteer are brutally murdered while caught in a compromising position. Written in their blood on the wall of the crime scene: IT’S GOOD TO BE BACK. And with that, a centuries-old horror known only as the Boogeyman returns to taunt Nathaniel Cade, the President’s Vampire. Against the backdrop of the 2012 presidential race, with the threat of constant exposure by the media, Cade and Zach must stop the one monster Cade has never been able to defeat completely. And they must do it before the Boogeyman adds another victim to his long and bloody list: the President of the United States himself.

It’s been four years since a new president ascended to the White House. Zach Barrows has not seen Nathaniel Cade, the President’s Vampire, since being fired from his position as Cade’s handler and sent to a small, cramped office in a government building in Nebraska. Once he and Cade fought a shadow war against the monsters, spies, and demons that threatened the United States. Now Zach pushes papers and listens to conspiracy theories from people who have no idea how dark the real world can get. Then Zach is summoned to the Situation Room by President Lester Wyman, who is both the commander-in-chief and a possible traitor. But he and Cade are bound to follow Wyman’s orders. They are told to find out why a top-secret missile silo has gone offline. If they fail, a nuclear warhead will launch, and the world will die in a hail of fire. In other words, it’s just another night on the job. After a long absence, Cade and Zach are back in action together—for what might be the last time.
