Each book in the Time After Time series follow a pair of quintessential lovers, Richard and Nicole, through their lives together, in different times, with different names, and sometimes even on different planets. This follows the alternative theory that the relationships we forge in this lifetime,both the good and the bad, are continued into the future, and are rooted in the past. How we live , whom we love, and the good and evil deeds we do today follow us into the future. Unsettled issues will present themselves again and again until they are ultimately resolved. Those people who have had a profound effect on us in this lifetime will find us again in the future.
