I just finished The Story Hour by Thrity Umrigar and it was captivating. I couldn't put it down! I'm about to start another one of her books - Everybody's Son. I also finished Penance by Kanae Minato but I didn't like it very much. I found it repetitive and slightly confusing, which may have something to do with the fact that it was translated from Japanese.
I absolutely love confetti cake and white cake with a custard layer.
