[EX Q]: The book was easy to read, and filled with valuable information that is worth the time spent reading it. I bought it in conjunction with a project, and, as part of it, read this very good guide on how exactly they did things down there at Area 52. Not only does he get his information, but writes it in such an entertaining way, even for non-scientists.
[EX A]: Good Review

[EX Q]: My son was very upset when the book didn't have pages. I called and received a new book, which also wasn't the correct book. Needless to say it will go in the garbage. What a rip off! They should take out all reviews that are not written by "Amazon Verified Purchase". This has never happened before.
[EX A]: Bad review

[EX Q]: Love this thing. It really has helped me keep organized.
[EX A]:
