Taint

When a mysterious, soul-eating force known only as the Taint threatens everything they know and love, Leo, a knight with fabulous hair and Tyler, a vampire with a sense of humor (he's not short. Don't call him short), must find the man with the Purity. The only trouble is, they're on opposite sides. As Taint razes the world to the ground, chosen ones are few and far between. So Leo might have to put everything on the line for a destiny that isn't his while Tyler drinks his way to victory. He's pretty sure he's going to pick up more gorgeous maidens along the way too.
