In Michael Crichton's Timeline, he uses the principles of quantum physics to take characters back in time to key points in human history. Robert Doniger has created a technology that can travel between multiple, almost identical dimensions to bring people to other times in history. His goal is to create theme parks, and he's invested billions in the technology and in archaeological investigations at sites that will become tourist destinations in his grand scheme. Everything begins to fall apart when some of his scientists travel back in time too many times, leaving clues that are found by the modern-day archaeologists. Professor Edward Johnston pays a visit to Doniger to find out what's going on. He's sent back in time to 13th century France so that he can see for himself, but something goes wrong and he's trapped there. His team is recruited by Doniger to go back and rescue him, and they have 37 hours to do so. Of course, everything goes wrong once they travel back in time and it comes down to the last few seconds before we find out if they get back out.

Like many of Mr. Crichton's other books, Timeline takes a topic of contemporary research and creates an alarmist premise around it. Similar to other books about time travel, this one creates situations that just can't be explained away; no amount of logic applied to it makes sense. In spite of that weakness, Timeline is an exciting romp through history that kept me turning the pages to find out how everything was resolved.
