I am going to check out all three, starting with Sophia, the biography of Sophia Duleep Singh. Sing, born in 1876, was the daughter of the last maharaja of the Punjab. According to The New Yorker's description of the book, Sing "was a trendsetter in everything from clothes to dog training. But by her early thirties she had joined the suffragettes, and she became a key figure in the movement." It sounds like an interesting life and I'm looking forward to reading this book.
