Morganville Vampires 5: Lord of Misrule by Rachel Caine

Blurb:

Morganville, Texas. Just south of normal.
In the coolege town of Morganville, vampires and humans coexist in (relatively) bloodless harmony. Then comes Bishop, a master vampire who threatens to abolish all order, revive the forces of the evil dead, and let chaos rule. But Bishop isn't the only threat.
Violent black clouds promise a storm of devastating proportions. As stundent Claire Danvers and her friends prepare to defend Morganville against the elements - both natural and unnatural - the unexpected happens: Morganville's vampires begin to vanish one by one. Discovering why leads Claire to one last choice: swear allegiance to Bishop... or die.

Review:
Dark, from start to finish. This town is strange in one more way than one, but the sense of knowing that when you go to give blood, it will go straight to someones lips. At first, I found it hard to get into but after sitting on my bed for an hour, I found it hard to stop. It was even more thrilling that the last book but the love story between Claire and Shane and the other between Michael and Eve makes your heart flutter and makes you go 'awww.'
A work of genius of Caine's front
