In the beginning of the book the writer explains how he comes to these prophecies in a very intersting prologue. The rest of the book has 13 chapters, each one of them has 13 verses with cryptic scripts. Yes, it's a lot cryptic but that's the fun of it.
I guess this book comes out at the perfect time, being 2012 and all. So if you are up for the challenge this is a book that can make your mind work overtime.
