This book was a really fun read. The story is well written and goes by quickly. If you've seen the Da Vinci code, this book is about the same premise--solving a mystery using ancient clues left by famous old people.
Brown says that his facts about Rome, Vatican City, the art and artists, and the Catholic church's rules and customs are all correct, which is what made this book so interesting to me. I recommend it highly to anyone who is interested in the origins of the early Catholic church or Roman history.
