Full disclosure: I'm friends with the author (and apparently inspired the titular character's name somehow).
This is one of the most whimsical things I have ever read, and I expect no less from Ms. Hall. I love not only the charming narrative tone and the humorous situation poor Dinkums finds himself in, but also the melding of magical and modern. This is no Harry Potter knockoff.
This is a story about being careful what you wish for, about fast friendships, family ties, and learning to love yourself. It's absolutely heartwarming and entirely worth reading. I couldn't ask for a better story about dragons.
