Yaa Gyasi, "Transcendent Kingdom" in conversation with Tayari Jones, author of "American Marriage."

Yaa Gyasi's stunning follow-up to her acclaimed bestseller "Homegoing" is a powerful and intimate novel about a Ghanaian family in Alabama. Gifty is a PhD candidate in neuroscience studying the neural circuits of depression and addiction. Her brother, Nana, was a gifted high school athlete who died of a heroin overdose after an ankle injury left him hooked on OxyContin. Gifty is determined to discover the scientific basis for the suffering she sees all around her. But even as she turns to the hard sciences to unlock the mystery of her family's loss, she finds herself hungering for her childhood faith. Exquisitely written, emotionally searing, "Transcendent Kingdom" is a deeply moving novel about faith, science, and family.
