I just finished listening to Ishmael Beah read his book, A Long Way Gone. Oh, that book was hard. It's a first-person account of the author's childhood during war in Sierra Leone, including his years as a child soldier. It's the kind of book that makes you feel like crying on every page. It's hard for me to comprehend that it even happened.
Despite the above, I do recommend it. It will change your perspective about things for a while.
