For me, I can't wait to read: The Secret Lives of Baba Segi's Wives by Lola Shoneyin. Due out June 29th from William Morrow, amazon says this about the book:
Blind acceptance splinters a polygamous marriage in Shoneyin's gripping debut set in modern-day Nigeria. Bolanle Alao, the newest and youngest of Baba Segi's wives, threatens to upset the balance of power--she is educated and beautiful, though naïve about the relationship dynamics among the other three wives in the house. Raped at 15, Bolanle considers herself disgraced and unwanted until Baba Segi, an overweight, malodorous businessman welcomes her into his family, no questions asked, until it seems she cannot conceive. Like the other wives, she feels she has been saved by Baba Segi, who accepts all of them politely, but beyond brief mentions of his sexual encounters and visits to the toilet, Baba Segi is a peripheral character. When greedy Iya Segi and Iya Femi plot to run young, sweet Bolanle out of the family, the result is disaster. It is Bolanle's unexpected submissiveness that leads her and her husband to uncover a secret that forces him to assert his control over the family. Shoneyin masterfully disentangles four distinct stories, only to subtly expose what is common among them.
