History major, Elizabeth Grace has always been exceptionally good at the subject. No matter the era, she remembers the past as if she belongs there... Just when Lizzy is in the thick of her studies at Knox University, her life takes a turn backwards. Literally. Lizzy finds herself hours behind everyone or hours in front. She can't explain it. Nor can she explain her attraction to the alluring new Dean of History, Phillip Desmond. Phillip's timelessly attractive, curiously young and has implemented a peculiar exchange programme. Soon, Lizzy learns that these "exchange students" and Phillip are not who they say they are but are in fact, part of an extremely rare and secret group called Time Keepers: individuals who belong in the past. Their purpose is to ensure history takes its course and Lizzy is one of them. Lizzy's passion and knowledge of history is going to help but is it enough to prepare her? Will she discover the era she belongs? Will history take its course?...
