I love this book because it was so good. I can't actually tell if it was a sad ending or a happy ending. You can't ever hate this book because it has a great (or the greatest) plot. The first part of the book was Hilary and her best friends hates Sarah-Kate. but Hilary is beginning to like her. Sara-Kate had found elves building houses. Hilary was the only one who can go over and look. but her friends don't agree...
So, read the book to find out!
