This affecting novel follows Gifty, an Alabaman daughter of Ghanaian immigrants, who is pursuing a PhD in neuroscience. Her passion stems in part from her brother's death as a teenager due to an overdose. 

The story is slow-moving, reflective, and tenderly poignant. Gifty spends much of her time attempting to find a bearable balance of her faith and her profession. She struggles with the questions that plague her — first as a girl in youth group, implacable by platitudes but desperately eager to be good, then as a scientist, guarded yet drawn to the beautiful, comforting mystery of belief. 

Part of what makes this book so good is that it is simultaneously simple and extraordinarily perceptive. There is no major driving plot. You know most of what will happen before it does. And yet, ultimately, Gyasi found a way to engrossingly bring us along on the introspective journey of an earnest, thoughtful, brilliant woman sorting through her pain and grasping at hope.
