I don't often do reviews, however, I stared this book on Saturday, it is now Sunday evening and I have finished it. I had trouble putting it down. My laundry didn't get done because I just wanted to get back to the book! This is the first book of Sarah's that I have read and I guarantee you, it won't be the last! I can't wait for the next book!

positive
