The Most Rapid and Direct Means to Eternal Bliss?

[Unknown51]

Has anyone read "The Most Rapid and Direct Means to Eternal Bliss" by Michael Langford? I just came across it the other day on Amazon, and overall, it seems to be getting pretty good reviews from the people there. However, I haven't heard much about it from anyone else. Any input from someone who has read it or has heard about it would be great. Thanks!
