Blood Oath is a cross between a political thriller and a vampire novel. A vampire who has served American Presidents since Andrew Johnson is caught up in a conspiracy at the highest levels of government involving the original Dr. Frankenstein, a shadowy off-shoot of the CIA, Middle Eastern terrorists, and most likely the Vice President as well.

Overall, it is pretty formulaic. But it delivers well on the formula with short, effective chapters that read like a screenplay. It ends with a global montage that dangles several loose ends for sequel(s) -- but as much as I enjoyed this one, I don't think I'll be reading the next because it won't have the most interesting parts of this which were the backstory, the creation of a believable vampire world, etc But I'm glad I read this one.
