it's the second book in the Subgenius series
the first book is simply called The Book of the Subgenius
from the author:
Its hour come round at last: the prophesied do-it-yourself end times religion for swinging mutants and terminal abnormals! Eternal Salvation- or triple your money back. Beyond science, reason, and orgasm. Instant instructions for those who follow no master! Scarier than the Old Testament and Scientology put together! More needlessly complicated than the Qabbalah! More vague and ambiguous than the I Ching or astrology! More sheer, brazen hogwash than even the Book of Mormon-- yet infinitely more accurate than Project Bluebook and the Warren Commission Report-- combined! Authorized to blaspheme by the gods themselves! Compatible with all major world religions and most weird fringe cults with a minimum of expensive interfaces or messy surgery.
and holy fuck amazon.com has copies for .49 cents right now lol
