I couldn't put this down! As a kid I LOVED the movie, so I was stoked to actually read the book. From my memory the movie follows the book pretty well, although it's been a decade so I could be very very wrong. Timeline combine history, archaeology, and science to make this an action packed historical/ science fiction thriller. Fourteenth century France comes alive for a team of archaeologists. They had no idea that the site they were excavating could still theoretically "exist." When their team lead, the professor, goes missing, the team travels to the headquarters of a multi-billion tech corporation that has been funding their digs. Little do they realize that all their historical knowledge and expertise is about to come into play when they are transported back to France, only this time, it's 600 years earlier and the castles they have been excavating are still standing. Timeline is fast paced and fascinating, the history and science blend together to make a compelling action thriller. I definitely need to re-watch the movie now!
