Yep. I totally called it. I was exactly right on who sent the letters.
I'm also torn on how I feel about this book. I enjoyed this book but I found a couple of minor editing errors. And the plot was pretty basic. It was a fun, simple read but nothing super deep. I don't think it was worth all the hype. The ending didn't seem to really wrap up anything. So I will read the next book but I hope some stuff gets cleared up.
I also hardly liked any of the sisters. Just sayin.
