Perhaps these vampires are not of the supernatural variety, but there are people who believe there is a noble heritage which supports the drinking of blood.
Vampires hate country music.
Vampires are delusional freaks who are having their beliefs validated by getting to be the subjects of a book. Not once do the authors give the subjects the scornful drubbing they so desperately need. Instead, they indulge their every statement, then spit it back to us at a sixth-grade reading level. Something in the Blood is shoddily researched, poorly organized and badly written. The only thing worse than the stroking of the vampires must have been the stroking of the authors by the publisher, who should have passed the book along to a well-paid team of editors to bang some sense into it.
