The Memory Keeper's Daughter

The Memory Keeper's Daughter by Kim Edwards was recommended by a friend from my last job. She says that it does a great job showing the continuing impact of secrets in a family. The plot concerns a set of twins, the son healthy, the daughter born with Down's Syndrome. The father, a doctor conceals her birth, telling his family the baby was stillborn. He arranges for a nurse to have the baby institutionalized, but instead she decides to keep the child. These decisions have a huge impact on the direction all of their lives end up taking.
