Query: Not just for kids

Great book, fun reading and not only for kids, that's why I read it. The author has hooked me with the first book, and I inmediately bougth the rest of them. I enjoyed reading the book, but honestly, the first one was better, I think it was a matter of discovering a "new world". The second book shows again that same world, with a few additional things going on, but not the "magic" discoveries I had expected to find. I trust the third one will be better, no doubt. Congrats to the author! Impressive success!
