Timeline (1999) by Michael Crichton is a science fiction thriller that blends historical fiction with quantum mechanics. The story follows a group of graduate students from Yale University who use time-travel technology developed by the ITC company to rescue their professor, Professor Edward Johnston, from 14th-century France. The students are sent back to the year 1357, where they navigate medieval politics, chivalry, and danger in a quest to save their professor and return to the present. Themes explored in the novel include medieval technology, time travel, and the similarities between the past and present. Despite mixed reviews, Timeline was adapted into a video game and a poorly received film.
