I have read many Gernimo Stilton Books, But I have never actually read a Thea Stilton Book. For the first Thea book i've read, I would say this book is a page turner! It has so many interesting clues and facts about different things in the book.My favourite part is when they figure out where Hans Ratisson disapeared to. I also love how she puts a little magnafine glass wherever there is a clue. Then later on in the book she puts a box to review the different clues. thea stillton and the dragon cove was so amazing .i thought the beginning was great how thea was an honor student and then comes back to be a teacher was my favorite part.One of the cool things is the thea stilton actucal wrote the book went she was in the story too.this story is all about these five mouses in the school find a hidden passage way in the dragon room. If you want to fine out more about the book .you have to read is !!!
