Sort-of enjoyed this more than I wanted to.
Not a huge fan of drawing straight-and-easy morals from the lives of ordinary saints, but I found the variety, tenacity and resourcefulness of these women helpful. They faced diverse circumstances and patterns of married life with grit and grace (or so it seems, there's a bit of an overreliance on early, adoring biographies). But we get some honest talk about their foibles and faults too.
It's refreshing to see the considerable labour and wisdom of women who are generally overlooked in favour of their famous husbands. And the author neatly explains the contemporary context with a historian's eye. Just wish she hadn't used so many exclamation marks, which felt a bit patronising.
