Bill, the Galactic Hero: Planet of Tasteless Pleasure [EPUB ebook] 

He’s the perfect Spaceship Trooper: big, strong, and completely brainwashed. He’s the perfect hero: willing to do almost anything to save his neck (perhaps one of the only body parts that’s still his own.)Bill is in the hospital, vainly hoping for a real foot to replace the satyr’s foot he’s been lumbered with. Not that he has anything against satyrs – at least not until one grabs him by the foot and pulls him under the ocean. Into a world of unspeakable and endless pleasures! Roaming this dimension of primordial desires, Bill faces dragons and gunslingers for the sake of true love – and a really good beer!
