This book is, simply put, amazing. It has so much information in it's tiny package. I knew of several of the end of world predictions, but I had no idea that there were so many! It's not every one ever written, of course, but it's a very titillating sampling that, in some cases, had me digging up info in certain directions out of curiosity. The book is written for humor, and it really seems to succeed well! I loaned it out twice, and got great reviews from both people. The second never returned the book, so this is actually my second time purchasing it. It's definitely a book I like having on my shelf, but I love sharing the interesting thing with other people too, so I may be back again in a few years. If you want a relatively quick, easy to swallow read that goes over a large chunk of religions and their end of world predictions, this is a must read!
