I devoured this book, and I suspect it will stay with me a long time. It's incredibly comprehensive in its examination of humanity's obsession with our fore-bearers—from ancestor worship to made-up pedigrees to the problematic ethics and dubious science of sites like 23andMe. Newton also tackles her own obsession with her thorny family tree. Her dad is a strident racist and angry narcissist; her mother is a preacher who sees literal demons on people's shoulders; previous generations include murderers and slave-holders, mental patients and witches. She tries seeing them through a variety of lenses, but her eyes are always wide open and prepared to accept difficult and multiple truths.
