This was one of my favorite Rinaldi books, out of all 12 that I've read. Emily Pigbush's mother dies in the beginning, and she has to choose between living with Annie Suratt, Mary Suratt's daughter, and her Uncle Valentine, a very good doctor. When she ends up unwillingly staying with her Uncle, she learns something terrible about him, that forces her to run away. When his assistant finds her and brings her home, Emily discovers that the crime her uncle commits is for the good of everyone. I don't want to give it away, but this book is fascinating, and I forgot to say that it is during the time of Lincoln's assassination. I would reccommend ALL of Rinaldi's books, even though I haven't read them all. I just know they're good anyways!
