Author Charmaine Wilkerson's new novel, Black Cake, is all about identity; who we are and how we fit into this world. Estranged siblings, Benny and Byron are left a recording by their late mother after she dies. The recording is full of secrets about their family that force Benny and Byron to reevaluate everything about their lives. Wilkerson told NPR's Kelsey Snell that even though Benny and Byron didn't know everything about their mother, she is still their mother who loved them very much, and that's also a part of their identity.
