I got Stephen King’s 11.22.63 for Christmas, and I just finished reading it last night.
It’s basically about a teacher who gets a chance to go back in time and save JFK’s life. It appears to be well researched and it’s quite a page-turner (although I think the ending is weaker than the rest of the book).
My only real criticism is that the main protagonist (born around 1975) seems to be a little bit too comfortable with life around 1960. Could it be that Stephen King forgot that 1960 isn’t a sweet childhood memory for a child of the seventies in the same way as it is for a baby-boomer like himself? I definitely would be much less worried about trying to fit in around 1980 or 1990, because of have memories of that time.
It’s well worth a read, even if you aren’t particularly interested in Lee Harvey Oswald and John F. Kennedy.
