"In this courtship and marriage biography, the author examines an unlikely but powerful bond between cousins, the Origins of the Species scientist and the religious devotee love of his life. Beginning with Darwin's 'to marry or not to marry' pro/con lists through Emma editing Charles' autobiography so that it would be less 'offensive,' the couple provided for each other sounding board, respected opposition, and beloved soulmate . . . The volume provides a unique blend of romance, scientific observations, explanations of medical practices prevalent in the early-nineteenth century, and opportunities to examine scientific discoveries and religious beliefs in detail."—Patti Sylvester Spencer, VOYA

“Ed Regis is always a careful researcher, always an independent thinker.  In this subversive little book, he shows that the biggest of big questions is still worth asking—more urgently now than ever.”—David Quammen
