The Good Sister (Paperback)

Fern Castle works in her local library. She has dinner with her twin sister Rose three nights a week. And she avoids crowds, bright lights and loud noises as much as possible. Fern has a carefully structured life and disrupting her routine can be . . . dangerous.
When Rose discovers that she cannot fall pregnant, Fern sees her chance to pay her sister back for everything Rose has done for her. Fern can have a baby for Rose. She just needs to find a father. Simple.
Fern's mission will shake the foundations of the life she has carefully built for herself and stir up dark secrets that she long thought were buried.
