Amy Waterman had always been dedicated to her job as a biochemist at BioTime Labs. Of course it was the kind of work one could get dedicated to - saving the world, or least, curing diseases that afflicted the people of her time, in 2066. BioTime's business was to find plants whose chemical composition could be used to synthesize such remedies. All the plants studied were now extinct so to retrieve a specimen, one had to travel though time.
Amy was not supposed to be one of the first time travelers.
