This is an awesome book. The Thea Stilton books are a great addition to the existing Geronimo Stilton series of which is still growing. Thea Stilton and the Dragon's Code introduces readers to the new characters. Thea's 5 students are all very different from each other, but because of their differences, they each have a different perspective when solving a mystery. All of the introductions don't seem to take away from the mystery. I love the 2-page illustration spreads. I still like the different fonts and colours on specific words too. It makes reading fun. The hints are well presented throughout the book, and I find the number of hint reminders that one comes across is quite decent too. All the hints "clicked" together as I got closer to the end of the story. This book/series is meant to be girlier than the Geronimo Stilton books, and I think it's appreciated and well-received. Girls can be great detectives and solve incredible mysteries, but perhaps most of all, the only way to solve a mystery and have fun while doing so is with amazing teamwork. (bambireads.blogspot.com)

I have to agree with another reviewer, as an adult, these books don't make a huge impression on me, but kids between the ages of 7 and 10 LOVE Geronimo and Thea Stilton. Done in full colour, the bright pictures, big text (and some very cool, and helpful, fonts/colouring/mini-pictures of some words) are good. Add in clues that kids have to look for as they read so they can solve the mystery along with the protagonist and you've got an amazing book series.

I went to Chapter's today and saw this book with a very good price. It said in the USA it was 6.99 dollars, and in Canada it was 7.99 dollars. In my opinion that is a very good price. HCS

Okay, I admit that as an adult, I don't find the Geronimo Stilton, and now his sister, Thea Stilton, too interesting. However, my dauther, and perhaps the entire 1st, 2nd and 3rd grade LOVE them. Combining colourful design and fonts with mystery-solving seems to really work. Kids trade them, talk about them. And they are non-violent, and sometimes, sometimes, funny.
