What this book is about
Fern Castle has always been the one who needed protecting — her twin sister Rose has looked after her their whole lives. When Rose confides that she desperately wants a baby, Fern sets out to give her one in the most unconventional way possible. Told in alternating timelines — Fern's present and their mother's diary from the past — The Good Sister reveals slowly what the sisters are protecting each other from and what their mother was hiding. Sally Hepworth's domestic thriller is a methodical unraveling of the stories families tell to survive.
