Book excerpt: Elizabeth Buchan’s beloved bestsellers, Revenge of the Middle-Aged Woman and The Good Wife Strikes Back, have made her an icon of upmarket women’s fiction. Taking her characteristic wit and emotional resonance to a new level, her latest novel focuses on two lives separated by forty years of history. In 1959, a forty-something married mother finds herself immersed in a surprisingly passionate affair with a younger man, while in the present, a professional woman faces a daunting choice between her blossoming career and her husband’s desire for children. Mirroring each other in surprising ways, these twin stories offer a deliciously readable funny and moving look at the battle of the sexes across time—and deliver another smart, nuanced novel for Elizabeth Buchan’s growing fans.
