I remember Biafra

I remember as a child, watching news-clips about the civil war in Nigeria and seeing starving children from the secessionist state, Biafra. Chimamanda in Half of a Yellow Sun is educating me on this aspect of Nigeria's history in the sixties. The horrors of the war is graphic.  The book is very well written.  I am totally absorbed in this historical fiction that is wrapped up in a love story and a story about social life and family life in Nigeria.  Something has happened to the main characters. I don't know what it is at this point and I am eager to find out.  Richard, a socially inept British expatriate, and Kainene are lovers and he has fallen out with a revolutionary professor who happens to be the lover of Olanna, Kainene's twin. Whatever the quarrel was about, Richard no longer visits the professor's home and when he sees Olanna, he tries to avoid contact. I am invested in these characters. Loving it.
