Read it, the book is Pro-Masonry. It is very interesting. Clearly a work of fiction, much more so than the "Code" was. I think if you are on here, you have demonstrated your ability to read, write and an extrordinary interest in Masonry - get it read it, compare it to what you know.
My plan is not to try to debate the book with non-Masons, not to address anything that is or is not secret, not to point out the errors, but to use it as a recruiting tool. Just remember the EA charge about those whole disparage through ignorance.
Overall, very good read regardless of Masonic affiliation. Mine is an eBook, really enjoyed that as well.
