Over the course of a week­end, two cou­ples reck­on with the long-hid­den secrets that have shaped their fam­i­lies, in a charged, poignant nov­el of moth­er­hood and friend­ship. Unwind­ing like a sus­pense nov­el, Joan­na Her­shon­’s St. Ivo is a pow­er­ful inves­ti­ga­tion into the mean­ing of choice and fam­i­ly, whether we ever know the peo­ple clos­est to us, and how, when some­one goes miss­ing from our lives, we can ever let them go.
