12 July, 1939, Perry Nelson is driving along the palisades when a tyre blows out and his car careens off the road. The last thing he sees before his head connects with the boulders below is a girl in a green bathing suit. When he awakens, the girl in green is a woman dressed in furs and the sun-drenched shore has transformed into snow-capped mountains. Perry's confusion is cleared when the woman, Diana, shares a vital piece of information: the date is now 7 January. The year...2086. Perry's swift education in the ways of the modern world emboldens him to assimilate twenty-first century life. Yet his knowledge of a bygone era will serve him best as he leads his newfound peers even further into the future than they could have imagined.
