Replay by Ken Grimwood

3.0

Ever seen the movie Groundhog day? I know the movie came out LONG after this book was published, but hear me out: In the movie Groundhog day, a reporter is experiencing the same day over and over again in an endless cycle. When he crosses the street he bumps into the same old friend from high school, he is on his way to do the same job every day, there is always a blizzard at the end of the day...And when he wakes up the next morning, the very same thing happens again.

Replay follows a similar pattern: Jeff always die at the age of 43. No matter how well he takes care of himself, he dies.... And wakes up as a 17 year old kid.
He relives his life from 17 onward until he is 43, when he dies.... And wakes up again.

Personally, I was more interested in the speculation as to what really was going on. And that only came into play later in the novel, when Jeff meets another "Replayer", and they share this experience.
However, when I got through the middle-mark, the book suddenly became very interesting!
