The Rule of Four by Ian Caldwell, Josh Hamilton, Dustin Thomason

A mysterious coded manuscript, a violent Ivy League murder, and the secrets of a Renaissance prince collide in a labyrinth of betrayal, madness, and genius.


Princeton. Good Friday, 1999. On the eve of graduation, two students are a hairsbreadth from solving the mysteries of the Hypnerotomachia Poliphili. Famous for its hypnotic power over those who study it, the five-hundred-year-old Hypnerotomachia may finally reveal its secrets -- to Tom Sullivan, whose father was obsessed with the book, and Paul Harris, whose future depends on it. As the deadline looms, research has stalled -- until an ancient diary surfaces. What Tom and Paul discover inside shocks even them: proof that the location of a hidden crypt has been ciphered within the pages of the obscure Renaissance text.

Armed with this final clue, the two friends delve into the bizarre world of the Hypnerotomachia -- a world of forgotten erudition, strange sexual appetites, and terrible violence. But just as they begin to realize the magnitude of their discovery, Princeton's snowy campus is rocked: a longtime student of the book is murdered, shot dead in the hushed halls of the history department.

A tale of timeless intrigue, dazzling scholarship, and great imaginative power, The Rule of Four is the story of a young man divided between the future's promise and the past's allure, guided only by friendship and love.

This book left me wondering if all those professional reviewers that gave it excellent reviews weren't afraid of being labeled not intellectual enough to "get it." The book is continuously compared to The DaVinci Code, but while Dan Brown's book may not have been a literary masterpiece, it was fun. The Rule of Four is so tedious in places that I can see why some people don't finish it. In this book, we aren't solving puzzles to save the world, we are simply trying to finish a college thesis on time. And it's a thesis on a very boring subject, at that.  What really killed this book for me was the extremely detailed and painstaking descriptions of relationships and personalities. I found myself peeking ahead to see how much longer it would go on and if things would improve. A few times I stopped to read other books, and then went back to it with a sense of dread. Penny pincher that I am, I can't pay for a book and not finish it, so I finally made it through. I recommend this book for insomniacs.

I too got it because of all of the comparisons to The DaVinci Code. As has been said frequently here, the comparison is not warranted. Yes, The Da Vinci Code may not be a masterpiece of literature, but it had intrigue, excitement and yes, puzzles. Lots of them. The puzzles, what there were, in the Rule of Four played a seemingly trivial part of the narrative. The emphasis of the book was more a highly detailed and tedious examination of a troubled young mans social interactions. I also particularly didn't like the fact that virtually the entire book is written as flashbacks that not only jump around in time, but give no clear indication that they are doing it. I kept finding myself half way into a section before I could figure out how it related to what came before.

A constant reader, I am always looking for something special to really grab my interest. This book did it. I found the book well-written, well-paced, and somewhat genre-defying. I enjoyed going back (via the story) to campus life to tackle this intellectual mystery. The characters and the plot do take us out of the humdrum, but isn't that what a good book should do? A good read.

i don't agree with other reviews that describe this book as poorly written and boring. maybe the beginning of the story was a bit slow to start, if you want to get really picky. once i got sucked into the story, i couldn't put this book down! even long after i finished reading it, i found myself thinking about the puzzles and riddles in the story.

I purchased this on a whim and genuinely tried to muscle through it but, it was too slow to build momentum and left me waiting for a suspenseful plot to develop. Readers of Dan Brown will be bored to tears...

I like a clever book that takes somthing real and wrap it up into a creative fictional mystery. This story feel short of that.

The important characters in this book are Tom, Paul, Charlie, and Gil. This book is historical fiction. In the story, Paul and Tom are trying to figure out the meaning of an ancient book called the Hypnerotomachia Poliphili. They face many challenges, twists, and turns along the way. The mystery of the purpose of this book is famous. On a scale of one to ten, I give this book a nine. It keeps you on the edge of your seat the entire time and you never want to put it down. The many bumps in the road that Tom and Paul travel are interesting and exciting. This book is three hundred and sixty-eight pages long. It is difficult if you don¿t take your time to read because of all the changing events. I recommend this book for people who enjoy reading historical fiction or about male friendship.

I got this book for Christmas along with 'Angels & Demons' and 'Jennifer Government'. For the most part I enjoyed this book. However, the synopsis is a little misleading. The synopsis depicts a story with a lot of action and on-the-edge-of-your-seat stuff. This was only slightly true. The book dealt mostly with the personal issues of the main character, Tom, and not the actual subject of the story. The plot was well told , but it moved much to slow for my tastes and did not deliver enough suspense. Worth a read, but only borrow it from your library.

I also picked up this book since I enjoyed the DaVinci Code. If you're expecting another DaVinci Code, you will be sorely disappointed. But if you can approach this book without comparing the two, I think you will enjoy it as well. It is a much slower story than Dan Brown's novel since it spends just as much time (if not more) on character development. I found myself drawn into the story because of the fact, the 'murder mystery' aspect is almost a secondary story in my opinion. I thoroughly enjoyed learning more about each character and his relationship to the others in the novel. I highly recommend this book as it is an easy read as well as an interesting one. But it is a slower if you're looking for past-faced action adventure, try something else. :-)

I found it rather boring and misguided.

I have never read "The DaVinci Code" so perhaps that allowed me to read this with an open mind. I found the book enjoyable and entertaining. I love their use of the English language. It was not the BEST book I have ever read but it was good. Certainly parts were slow but I got through them.

Out of the hundreds of books on my bookshelf, this is the one I've read the most. I love a book that makes me think, and I found myself trying to solve the clues before the characters did. The ending is so well-written that I turn to it again and again for a little smile. For their first book, these authors knocked it out of the park and I can't wait to read more.
