Finished Half a Yellow Sun by Chimamanda Ngozi Adichie and loved it. It's quality writing but very readable, and is centred on the Nigerian-Biafra War of 1967-70. The half-sun is the Biafran emblem. There are strong characters whose lives you really care about, as well as an honest depiction of the war later on in the book. It describes how the characters are affected by it, and is unflinching without being gratuitous. I highly recommend it
