A fiction based on non-fiction events. Background is the civil war in Nigeria with the formation of the country of Biafra (briefly) by the Igbo people. However, the emphasis is more on the relationships between two twin sisters and their partners, parents, family and friends. The author, an African, did an excellent job of portraying the events without making the book tedious, i.e., it remains a fiction/fast-read. A great balance of expressing the tension between modern and ancient Africa, as well as the underlying differences in class, religion and tribal/ethnic identities. I actually would have loved it if she had added an appendix or an intro chapter with more historical information about Nigeria and it's different tribes but it's not a big flaw.
