Dr. Robert Langdon wakes up in a hospital in Florence, with no memory of what happened in the past two days and how he reached here. Barely in his senses, he is attacked by a police officer. And, is saved by Sienna who is part of the hospital staff.

Sienna and Robert are rushing from one place to another trying to gather clues to understand what is going on. Things get crazy when they figure out that he was recently dispossessed of a deadly virus, and now the entire human population is in grave danger.

Will he be able to save the world?

Rating: Yellow - a decent follow up to the Da Vinci Code and Angels and Demons. Keeps you engaged, but by now you already know what to expect from this series so all the twists and turns are more or less predictable.
