Query: I disagree with most reviews

I just finished this book yesterday. I was always a huge fan of Jeanette MacDonald and Nelson Eddy, but now I just can't watch their movies anymore. I can't enjoy them because as I watch, their sad (tragic, really) history comes to my mind and totally ruins the movie. I would suggest that if you are a fan as I was that you don't read this book. It's not really about love. It's about obsession; and there's a huge difference between the two. The word sweethearts has a positive connotation, while this book brings with it so much negativity, it was difficult for me to read. I realize that I should have stopped reading near the beginning, but it's hard for me to put a book down once I open it. So if you're just interested in movie history, you may want to read "Sweethearts", but if you really enjoy watching the movies, I'd suggest you skip this book and find something else to read. I wish I had.
