How do you know who the good sister is when you can't trust anybody? Sally Hepworth's latest, The Good Sister, features the dual perspectives of twin sisters Fern and Rose. Fern works in the local library, avoiding crowds, sticking to her routine, and having dinner with Rose three nights a week. But when Rose discovers that she can't get pregnant, Fern sees this as a chance to pay her sister back for everything she's done for her — she just needs to find a man so she can have a baby for Rose. But when dark secrets from the past are brought to the surface, you'll soon discover some things are not always what they seem in this suspenseful tale.
