Book 10 of How to Train Your Dragon. This book starts the conclusion that will happen in two books. There is plenty of adventure and danger in this one. That said, this one begins to give us a foreshadowing of a not so happy ending. Since this is historical fiction and there are no dragon’s now, we can assume it is not going to be the ending we would all like. That said, I am excited to see how the series concludes over the next two books. I love that Toothless is still at the heart of the quest.
