Out of the series so far, this is my favorite. I had noticed that the relationship between the cousins was nearly perfect. They rarely disagreed or argued. And you know the saying about close quarters and all that. Well, this book shook things up a bit. There were heavy disagreements and some sharp words. Don't get me wrong, arguing isn't good, but it really made the characters more realistic. The mystery for this book was also baffling and I really enjoyed it. Onto book 4!
