Restoring Grace is about a picture restorer and a wine expert.  I already had quite a lot of wine experience but I really wanted to become a picture restorer while doing my research.  Two women who agree to live together in a beautiful old house owned by one of them are joined by a troubled teenage girl who is the step daughter of one of them.  I loved the research and putting three very different young women together.  Friendship is a great subject for a novel.
