Sandra McBride

 was a 20th century human.

She and some Mods and Rockers were transported by a Maker from 1965 Earth to an asteroid in the late 30th century. Eventually she married Alec Redshaw.

By 3012, the Makers realized taking the people from Earth was a mistake. They offered to let the people remain in the 31st century, or get sent back to their original time which would undo everything that had happened to that individual. This would cause them to have no memory of the prior 19 years. Sandra decides to stay so she will retain what she had learned, but Alec chose to return to Earth. (PROSE: The Space Age)
