Using her own life as a starting point, Rachel looks at the issues that arise for a woman in the years after she has lived the defining experiences of feminity. She writes about marriage, separation, motherhood, work, money, domesticity and love. Cusk considers the kinds of generational knowledge the contemporary woman harbours, the terrors or expectations that have been passed down to her and that are refracted through the modern transformation of female status.

Aftermath is written in the personal/political mode that characterised A Life's Work, Cusk's acclaimed book about becoming a mother.
