I had this book since 2006 and finally read it! I love dragons so that was why I bought it.
For a children's book it is quite interesting. I has a lot of different mythologies incorporated and it is quite adventurous. Sometimes the action descriptions fall short, but most of the time they make sense.
It's probably my own life situations, but the three main characters at first annoyed me in turn. Beatrice, who I like as a character annoyed me because she did not believe Daniel. I guess, she has been trying to act like an adult and take care of her brother for many years though.
Then Daniel annoyed me because yes he has a sense of adventure, but he should also try to protect himself! Even as a young child, preservation is there. Then Beatrice and Daniel annoyed me because had they communicated, it would have avoided certain misunderstandings. However, they do realize this early one and it gets better.
Dr.Drake annoyed me because he expected Daniel to do and not do things without explicitly telling him, forgetting his age. This too does get better! He truly does teach the children a lot. And this book is a good foundation for building a 'Dragonology' for us to understand the workings of their world.
The other characters, in their brief mentions, were also described a lot in a way. I like Alicia and her quick thinking at times and her and Beatrice showing Billy wrong. In the end, Billy does come around. Darcy is a great character that shows interest in learning and teaching. Emery and madam Gamay are also interesting and I hope to see more of them in the series. I also wish to see Beatrice's perspective as it would be interesting to be in her head.
I like how notes seem 'handwritten' and the dragon record book entries. They give the story more realness. I also liked the illustrations and pictures at the beginning of the chapters which along with the title give a hint of what's going to happen. Most of all, the Dragon behaviour was really interesting! Something which seemed strange was how they kept loosing their luggage and not worry. I get that they had bigger worries, but at least a mention should have been merited.
I think if you like A series of unfortunate events, dragon, and adventure, you'll like this series.
