Brad Meltzer is a best-selling author of both fiction and nonfiction. His latest, co-authored with Josh Mensch, is nonfiction: "The JFK Conspiracy." It's an easy read telling the story of how close JFK came to being killed...before someone else eventually did kill him. To me some of the most interesting parts are the law enforcement part of the story and how crazy it is that I've never heard of this story before.
The JFK Conspiracy: The Secret Plot to Kill Kennedy―and Why It Failed: Meltzer, Brad, Mensch, Josh (note: this is my Amazon Associates link so if you purchase through the link I'll earn a little bit of money. Of course you can buy the book another way if you object to that.)
