A Book that changed your mind about a particular subject (non-fiction).
Here's Jenn, sucking it up again! I don't really read non-fiction, and if I do, normally it's something I like and my opinion on it doesn't really change.
I have to say, I don't typically read a non-fiction book about something I am not interested in. I enjoy a good non-fiction. But I can't say that I ever read one that changed my opinion on the subject. The closest I think I could come to answering this question would be to say that I recently read JRR Tolkien: A biography, and while I already knew I was a big fan of Tolkien, this book made me love him even more than I already did because it made me feel like I knew him as a person. Great read, and I recommend it to all Tolkien fans :).
