This book was not what I thought it would be. My first impressions: it's about a young couple in Nigeria who vow to be monogamous in a polygamous society. If there aren't enough children, then marry another woman who will bear those kids. And when the couple are strongly coerced to bring in another wife by the family due to the fact that they have no children, things start to go in a very different direction than what I was expecting.
This is not a book like fifty shades, but I would definitely not suggest it to just anyone. There is nothing written for the sake of shock, but rather for the sake of explanation (although I don't think that I'm explaining it very well). It characterizes what people will be willing to do to have children, and the heartbreak of losing a child. Going back and forth between the characters was fairly confusing, but not detracting from the story overall. Oh, and Sarah Jessica Parker, who is a book club aficionado, recommended the book.
