The House in the Cerulean Sea

So many people have loved this book and I was afraid I was not going to be one of them at about halfway through. It was a good book and I was enjoying it, but I didn't understand what everyone was raving about. However, the last third of the book is so intense and really comes together in a way that I wanted to see. And yes, it made me cry...a lot. But in a nice way?
