Herschel's Adventures in Spaceland

Why is a mysterious couple trespassing in SpaceLand, a decrepit and abandoned amusement park that was inspired by the Space Race? And why is one of the trespassers decapitated? Why does Herschel Brilliand, Assistant Professor of Sociology, and one of the only people who wants to protect SpaceLand, find a bag of rotting chicken carcasses in his car? And why has SpaceLand drawn the malicious interest of corrupt college officials, meth dealers, the police, four different assassins, shady consultants, three different politicians craving the same Congressional seat, and two distinct (but similarly-named) cults that uneasily share a deserted department store?
