If I'm still young, I would love this book. However, I'm already old, not as in old, but a young adult. Still, I do enjoyed reading it. There's a lessons to it. If you are born with defect you just have to find a way to survive and live a fulfilling life. There's always an options. 
 The story is not realistic that's why the other unbelievable things is understandable. But there's one thing that didn't make sense to me. It's the communication of Louis to other swan especially to Serena and his kids. They can't read right? I was wondering if the sound of the trumpet is already a word for them? For example, if they heard "Ko-hoh" instantly they understand that it means Hello.? 
 hence, the story was good :)
