This is a detailed account of the untold genocide that occurred in Rwanda in the mid 90's. The author is a journalist and leaves few stones unturned in this harsh true story of horror. Definitely not for younger readers.
This is not an IR, but I've put it here because my favorite IR couple from the book prior to this -Carinian's Seeker- is mentioned quite a bit.
