You can pre-order the book today and it will be shipped to you upon its release on February 2, 2021. In the meantime, check out the author's website for a fascinating look at some of the real lives of characters in the book. The author has scanned images of photographs, reports and newspaper clippings, some of which detail the services that the American Library in Paris performed.
