Book 9 of How to Train Your Dragon. This book is the beginning of the end of the series. Finally we see Hiccup coming into his own. This book highlights his leadership and is a way the acceptance of the hero to his destiny, which is funny that it is happening 5 books in, but it works and the series is great because of it. I love how much it references previous books. Too much we see authors ignoring or forgetting previous books. This has great callbacks with references. I enjoyed this one.
