An institution to love and cherish

Books about marriage, like the battered old institution itself, come in and out of fashion with writers, readers and politicians, but never quite die away. These two, from the latest crop, are by women in early middle age, both experienced journalists with several books behind them; but Elizabeth Gilbert, a chirpy American describing herself as ‘a cross between a golden retriever and a barnacle’, is flamboyantly personal and unacademic, while the quietly British Kate Figes is a careful, responsible researcher and interviewer who keeps her own marital history to the margins.
