Query: This book filled in the "blanks."

I had watched the movie "Hotel Rwanda" a few years ago and this audio "fleshed out" that story for me. Very sad that all this killing and violence continues. Many gruesome details, but important for us to know. I've been on an Africa "kick" reading lots of books about different countries of that continent, some fact some fiction. Put this on your list.
