Replay

Blurb

Replay is a novel by Ken Grimwood first published by Arbor House in 1986. It won the 1988 World Fantasy Award for Best Novel.
The novel tells of a 43-year-old man who dies and awakens back in 1963 in his 18-year-old body. He then begins to relive his life with intact memories of the previous 25 years. This happens repeatedly with different events in each cycle. The premise was explored earlier by Richard A. Lupoff in his 1973 short story "12:01". The novel was a bestseller in Japan, and its time-loop concept has been referenced as a precursor of Harold Ramis' comedy-drama Groundhog Day.
