I had no idea what was going on in Rwanda, i.e. the genocide.
In fact I had really no idea about what happened until I stumbled upon the motion picture - Hotel Rwanda - recently.
My SIL actually went on a mission to Rwanda a year or so ago, to a village her church has sort of adopted.
She recommended that I read - Left to Tell: Discovering God Amidst the Rwandan Holocaust - the life story of a woman who survived the genocide by hiding in a tiny bathroom with 7 others for 3 months.
It's the sort of book that puts all of our trivial grievances (e.g. long lines at CVS, traffic,...) in the proper perspective.
I would say it falls into the *must read* category, for just about everyone.
