While on a field trip to New York's Museum of Natural History, Joe, Sam, and Fred travel one hundred years into the future, where they encounter robots, anti-gravity disks, and their own grandchildren.

Is it a love triangle if time travel is involved? Jeff Blue made important decisions every day—what clothes to wear, what to eat for breakfast, and what book to teach his high school English class. What he never expected was needing to make a choice between repairing his failing marriage in 1981 or start anew with J0—an unexpected and flawless copy of his wife in 2095. 114 years in the future is nothing like he imagined and waking up there comes with its own list of questions. But while getting back to his time should be at the top of his list, it's hard to resist the new-and-improved version of his wife. J0's a clean slate. A chance to have things just the way he wants, to have things as they were before their daughter’s “accident.” However, staring at J0 reminds him of the woman he had left back in 1981, whom he had vowed for better or worse. Armed with a one-way ticket to the moon, it's a race against the clock to seize his last chance to return home to his time. A time without hover cars, Justice Computers, TeleSkins—a time without J0. Is that what he really wants?
