Bubba and the cosmic blood-suckers / Joe R. Lansdale.

"Before Bubba Ho-Tep, there was Bubba and the Cosmic Blood-Suckers. Part of a secret government organization designed to protect civilians, Elvis Presley and a handful of hardcore warriors set out to save the world from an invasion of hive-minded, shape-shifting vampire-like creatures from a dark dimension who have taken up residence in a New Orleans junkyard. Besides Elvis, among these righteous warriors is a hammer-wielding descendent [sic] of John Henry of railroad fame, a Blind Man who sees more than those with sight, Jack, a strategic wizard, and Elvis's right hand man and journal writer, Johnny, all thrown in with Raven (real name Jenny) a female recruit who is also a budding pop star, and like Elvis, high on the charisma chart. Their leader is none other than Colonel Parker, Elvis's cutthroat manager, and a warrior himself, directly in contact with President Nixon, or possibly one of his doubles. It's an unnerving peek into a secret world, and a possible delusion. It's what happened before Elvis, aka Sebastian Haff, found himself in an East Texas rest home, mounted on a walker, fighting an Egyptian mummy and worrying about a growth on his pecker. Strange monsters, wild fights, sex with a beautiful ghost, a drug-induced trip into another dimension, and all manner of mayhem ensue, along with a Mississippi riverboat ride on a giant paddle wheel, and of course, there will be 3D glasses, fried peanut butter and 'nanna sandwiches, and a few hard working zombies. Bring the kids, but plug their ears and blindfold them. This is one wild and nasty ride to the dark side, but with laughter"--Jacket.
