A new book catalogs how a group of residents risked their lives to assemble a library in the middle of a war zone. In the midst of Syria's civil war, a group of residents in the war-ravaged town of Daraya outside of Damascus risked their lives to assemble a secret library in the basement of a destroyed building. Those actions are now cataloged in a new book called, "Syria's Secret Library: Reading and Redemption in a Town Under Siege." Hari Sreenivasan sat down with Mike Thomson, the book's author and BBC correspondent, to discuss.
