So of course, Harrison read this first and lent it to me. He is a Stephen King fan - big time!
I really liked it. I thought that I wouldn't because I really don't care about JFK. But it is not really about him but about a kind of time warp thing that allows this guy to go back to a certain date about 5 years before JFK dies. So his mission is to prevent the assasination. For some reason "time" and "reality" don't like to be messed with and tries to thwart his mission at every turn. It kept me engaged although I could have used about 200 less pages of details and side stories.
