If you like historical fiction, I highly recommend this book. Sophia is an engaging character. She comes from the Russian nobility and is constantly making small mistakes because of her background. She never expected to become a missionary and instead of a traditional Protestant background, she grew up in the Russian Orthodox Church.
The portrayal of the Ponca Indians is delightful. It's historically accurate and gives a very clear picture of what the Indians suffered after being deprived of their lands and placed in Agencies by the white men. If for no other reason, learning about the Poncas is a good reason to read this book.
I reviewed this book for the Thomas Nelson Booksneeze Program.
