Guided by a poem assembled from “compliments” paid by a suitor to his girlfriend (which echo the endearments Anna Karenina’s Count Vronsky directs toward his racehorse, before she collapses under his weight and is shot), You Darling Thing investigates bridehood and the concept of the vow through the voices of a variety of brides, ex-brides, courtesans, and wives. The book is ultimately less about marriage than about potentiality and promise, an engagement with what seems possible before it stops being possible—embryos that stay unborn, youthful predictions for a life before it’s lived, and delight in the expressive possibilities afforded by language and art.
