After Mr Marrs' book "Crossfire" (about the JFK assassination) was a hit, Mr Marrs asked his students what topic they thought needed a good look at. They all stated UFOs, and the result is the classic book "Alien Agenda". Like "Crossfire", "Alien Agenda" lets the reader decide for themselves what is going on. Mr Marrs offers a lot of information and many references in the back of the book. The introduction is about Mr Marrs going to New Hampshire and looking into a mysterious black cube found at the bottom of a pond by a farmer during winter. There is not much about the case as the government did their best to cover it up.
There are many such cases that do not get the usual exposure so many UFO incidents do. That makes the book quite interesting, as it is always a good thing to read about an encounter which has not been so widely reported. I do not want to give away too much, as I think most of the readers like to be surprised. A very entertaining book that should be sitting next to Mr Marrs' other book "Rule By Secrecy".
