Blood Oath by Christopher Farnsworth is a thriller with real bite. The first book in a three book series of supernatural thrillers that make you afraid of the dark once again.
Nathanial Cade is a vampire who has sworn a blood oath to protect the President from otherworldly monsters who threaten the United States. He takes his oath very seriously and tries not to drink human blood, the natural food for this apex predator. He is stronger than man, faster than man, and your natural instinct is to run from his otherworldly scariness. His liaison with the Office of the President is Agent Griffen, who has terminal cancer. Enter Zach Barrows, a political operative, who is tasked by the President to be the new liaison with Cade.
Immediately there is a threat to the United States from an unknown Arab group that appears to want to create undead Frankenstein monsters out of the parts of dead US servicemen. Cade suspects that the group needs Konrad, a diabolical scientist, who has worked for the Nazis and others, on human experimentation and worse atrocities. Konrad has the secret of re-animating the dead and turning them into mindless killing machines. It appears that Konrad, however, is being protected by both the CIA and another shadow organization in the US government that wants to control the country and will stop at nothing to achieve its ends. Konrad is more of a monster than Cade and Farnsworth is adept at showing the monsterous evils that man can achieve.
Farnsworth skillfully interweaves into the current story flashbacks to past instances where Cade's unique skill set has been called on to protect the country and also to highlight his back story.
Meanwhile the action in the present in this supernatural thriller is kept at a taut unrelenting pace. Doublecrossing politicians, secret CIA and FBI agents, murderous traitors to the United States, a lunatic fringe of Arabic killers, and Cade's vampire girlfriend Tania all face off in this breakneck thriller.
It will keep you up all night. A bright lamp might be a good buy.
