Caldwell’s The Rule of Four – 50 Book Challenge


The Rule of Four
Caldwell, Ian

This is one of those Dan Brown kinds of books mixing borderline plausible action with mysterious and arcane knowledge into a fun page-turner. It’s set almost entirely on and around the campus of Princeton University, which added to the fun for me. Perhaps not quite as polished as Dan Brown’s stuff, but a good beach-read kind of book.
