I absolutely loved this book. My wife bought me the illustrated edition for Christmas a couple of years ago (Christmas before last) and I just got around to finally reading before last Christmas. Many things came up, including illness, and I just finished it today. I read the print version of the book while listening to the audiobook.
The narrator is wonderful! It was never difficult to tell who was speaking during a dialogue scene. Even his female voices were quite distinguishable from each other. His pacing was just right for me; not too fast and not too slow.
I have read all of the Robert Langdon series of books by Dan Brown, and this is easily his best one since the DaVinci Code, which I also have in audiobook.
As the book opens Robert Langdon is in the hospital in Italy having been shot in the head. When he wakes up he finds that he cannot remember anything about the last couple of days. He meets Dr. Sienna Brookes when he wakes up, but barely has a chance to get his bearings and figure out where he is before a gunman enters the hospital and starts shooting up the place while gunning for Langdon. Sienna helps him escape the hospital, and this is where the adventure around Italy begins.
This book should NOT be missed. There are so many twists and turns and Robert Langdon is never sure who to trust or when to trust them. Fans of Dan Brown will not be disappointed by Inferno. If you can, get the illustrated version which has tons of pictures of the places and objects that Robert and Sienna encounter along the way.
