Pretty cool book. I bought it on the ipad last night and actually stayed up most of the night reading. very engrossing. If you're into the JFK stuff (I never really have been that interested), you'll probably LOVE it.
The guy is introduced to a hole that lets him slip back into 1958. He has to live for 5 years in the past, using gambling to live, then he follows Oswald thru his arrival in America, etc - all the way to the assasination - which is stopped.
I won't spoil it by going into the alternate history the book provides, but it is very very interesting.
Can anyone recommend any other good 'alternate history' books? I'm really liking this genre.
