On September 11, 2012, two American government facilities in Libya by an Islamic militant group. During the attack at the diplomatic building, United States Ambassador Christopher Stevens and United States Foreign Service Information Management Officer Sean Smith were killed. Images of Ambassador Stevens circulated around in the media, and it is a disturbing image. The militant group also attacked the CIA annex, killing two CIA contractors, Glen Doherty and Tyrone Woods. The fighting lasted thirteen hours, hence the name of the book. 

I bought this book after watching the film. I think the film did great justice to the book, and that was probably due to the fact that the survivors of Benghazi had a hand in both the film and the book. This story was so moving to me. It is unfathomable to me that these men went through this horrible event all on their own. I follow some of them on social media now, and I am glad that they were able to make it home and continue doing some positive things with their lives. The things that happened in this book are deplorable. It was a very suspenseful read, though that is nothing compared to those actually fighting.
