This is the story of Clare, a beautiful art student, and Henry, an adventuresome librarian, who have known each other since Clare was six and Henry was thirty-six, and were married when Clare was twenty-three and Henry thirty-one. Impossible but true, because Henry is one of the first people diagnosed with Chrono-Displacement Disorder: triggered by emotions and memories, his genetic clock resets and he finds himself misplaced in time. His disappearances are spontaneous and his experiences are unpredictable. Through Henry's time travel the couple attempt to live normal lives, but all of this is threatened by something neither can control.
