The Thirteenth Tale by Diane Setterfield
Vida winter is a reclusive author of many books and is famous for the mystery of the Thirteenth tale. Now elderly and dying she hires a young woman to be her biographer. She has always kept her past a secret. The young woman, Margaret Lea has her own secret of her birth. This all comes out in a very riveting tale. It is the pick of my library book group. It took me a while to get into this book but I am glad I did as it turned out to be a page turner.
