Girl in Hyacinth Blue is one of my favorite books. Just started Lisette's List. You write with detailed descriptions of time and place that pull a reader in but do not bog you down (I just came a cross a picture in a magazine of Roussillion and it was very much as you describe). Masterfully weaving fact and fiction. I am curious where/how you come up with your story. Is your interest in a place or time sparked first?
