I enjoy historical fiction and I loved this book. It is set in the early 1880s in the New York area. Two of the main characters are women doctors--one is a surgeon--and I learned a lot about women in the medical profession at that time.
The clear description of NY at that time, the politics and the politicians is an underlying story as is the story of 4 young orphans, a policeman who is a cut above the rest, classes in society, etc. The author did a great deal of research and it showed!
In all, it is a great story and I am looking forward to the sequel.
