The Rule of Four - Ian Caldwell and Dustin Thomason

My brother suggested I read this years ago when everyone (including me) was going through The DaVinci Code phase. But, for some reason, I put it off until now. This is the story of four seniors at Princeton, two of whom are obsessed with a little known Renaissance text that several scholars have spent their lifetimes trying to decode. The main character, Thomas, is obsessed with the book, to the detriment of his relationship with the one possible true love of his life. As Thomas's roommate Paul gets closer and closer to solving the mystery of the book, people around campus begin dying mysterious, yet inter-related, deaths. This book is a page-turner, but no where near as complex as The DaVinci Code. The puzzles within the book are not as interesting, and in the end what I found most compelling were the friendships among the four students, rather than the underlying secret of the text. I think this would be a good book for passing the time on a long airplane flight.
