Devereux: The Night Before Kismet, a Kismet Knight, Vampire Psychologist tale

Master vampire Devereux has it all: immortality, good looks, intelligence, money, a body to die for, and a constant stream of available women. Sounds like an ideal existence. So, what's the problem? He's listless. Bored. Unhappy. After 800 years, coming up with reasons to rise for another meaningless night can be a challenge, and he's starting to question his choices. Worried, two of Devereux's old friends concoct a creative plan to energize and encourage him to rejoin the land of the unliving. They don't want their friend to seek true death, so they're willing to do whatever is necessary. What could go wrong?
