Query: One of the worst books I have ever wasted my time on.

Really, I cannot explain what this book was about. It was partially about the testing of the atomic bomb, partially about some Indian chief who spent time in the brig and was rescued to go help the testing of this bomb, and partially about - well, I just don't know. The plot hopping is confusing, the characters not defined, the dialogue ridiculous, and the ending is the pits. Don't waste your time or money on this one.
