This is the story of Henry and Clare, who have known eachother since Clare was 6 and Henry was 36 and were married when Clare was 20 and Henry 28. This is possible only because Henry is one of the first people diagnosed with Chrono-Displacement Disorder: periodically his genetic clock resets and he flashes to other points in time.
