The description of some of the things in this novel, e.g. academic life, large corporations and search algorithms seem a little off, as if the author didn't actually know how they work. Unfortunately, some play a bigger role in the story. If you can suspend your disbelief about those the hunt for the mystery is exciting once the pace takes up. I did guess the main villain halfway through, though. While there are some ponderings about the purpose of maps the project one of the characters is working on - a map of everything - only gets a cursory treatment. It could have merited a book of its own.
