Book excerpt: In 1860s London, Arthur sees his wife, Emily, suddenly struck down by a pain for which she can find no words, forced to endure harmful treatments, and reliant on him for guidance. Meanwhile, in contemporary Perth, Alice, a writer, and her older husband, Duncan, find their marriage threatened as Alice investigates the history of hysteria, female sexuality, and the treatment of the female body—her own and the bodies of those who came before.
