Looking up the author is a bit baffling. They are a self-described "hindu anti-theist" who wrote a book called "Faith in Doubt" which looks to be about being anti-religion. What they are doing blogging about video game sites, I have no idea.
This is the best part though:
Must be a lot of silent fans out there, since "popular demand" amounts to zero reviews on Goodreads and two reviews on Amazon
The name is also a pseudonym, and they choose to be anonymous.
It's basically 6-7 books in one, I spent 4 years on it. Each "section" is a normal book-length size. Think of the value, not just the cost. It's well over the size of a normal 200-page book and goes into much more detail on the issues related to religion, which is after all a complex topic.
Also, there is a Kindle version. If you find that unsatisfactory, here's a detailed explanation from my blog of the pricing differences and why they were made that way.
