Notice Sciences. Plot was okay, book seemed a bit underdeveloped with a lot of mansplaining.

I have read Dan Brown for quite a while and usually enjoy his thrillers. I found this book took a while to get engaged with, but once I reached a certain point, the narrative sped up. The main story takes place over a twelve hour time frame, which did contribute to the mostly rapid plot line. But the technical explanations were just a bit of overload and, in my opinion, the book could have ended, only to have additional actions that did not really contribute to the story. This book took me at least sixty days to read and I usually read four books each month. If it had not been my book club’s selection, I would have put it down by page 60. I am glad I stuck with it and I am sure it will make a good movie, but I am not sure I would ever read again.

I really enjoyed the storyline but there were several areas of the book that just dragged mostly because the author over explained a lot of the more scientific information relating to the characters and their jobs.
