This book has a good concept, good story line, and good locations. The problem is that a base of science was used to make the story, but the author bastardized basic science whenever it fit his writing. Although the author gives special acknowledgement to his editor, it seems that the editor was out of the office the day this manuscript came through for review.
There are numerous basic editing errors, and there are many obvious basic errors in science: physics, chemistry, geology, etc. Even multiple errors with lie/lay, calling the National Park Service the U.S. Parks Service, no table of contents, apostrophes for plurals, etc. all made it past everyone involved.
The book sadly needed a science editor. The cryptozoology is fine and can work very well, but changing the ways of physics, computer science, etc. quickly brings a good fictional narrative crashing down for anyone with an education. Almost everything the author describes related to radioactivity, geology, computer science etc. is simply from his imagination, rather than based upon real life.
Super computers are not found in "clean rooms" as he describes, but in "raised floor" computer rooms. The people who access these computers are not in "clean suits" in the room with the computers, they are anywhere in the world, maybe in their underwear at home (yes, this was also true in 2007 when the book was released.)
Tritium is not found in quantities on cave walls, ore is not heated to extreme temperature by seismic activity, etc. There were so many ridiculous and absurd such references near the end of this book that I could not take it anymore and stopped reading. It had become a science fiction book describing another planet on which our scientific laws do not apply, so the logical, rational fabric of the Amazonian environment no longer applied.
