Timeline is a science fiction novel by American writer Michael Crichton, his twelfth under his own name and twenty-second overall, published in November 1999. It tells the story of a group of history students who travel to 14th-century France to rescue their professor. The book follows in Crichton's long history of combining science, technical details, and action in his books, this time addressing quantum and multiverse theory.
Since I like Timeline so much it made watching the movie so painful.
Read a history book. Hell, read Timeline by Michael Crichton.
If not, I recommend "Timeline" by Michael Crichton. It's not a taxing or immensely intellectual read, but it's a great adventure story with very interesting and suspenseful parts. It's a lot of fun to read and definitely won't feel like work - it'll feel like play.
