This book is a gem of a certain side of the universe because it leads him to discover he is approaching classic like Tolkien's books by its presentation of maps to locate the action, it amuses the child smells smelly and feel good (and some stink awfully, luckily the smell wears off pretty quickly after use for the child though it is a shame), small inserts to réflesion are to many interesting although I am not sure that the child's "collide" really.
On the other hand, the style of writing that is clearly fun for the child (and this is what counts), however sometimes adult side a bit ... heavy, heavy, heavy, heavy ...
One more is that despite its size, this book does not discourage the child from his reading, he wants to know later reread it ... Another little more, it's the end of the book Business operating that stimulates the child to ask you to keep cardboard, crepe paper to buy, find blueberries ....
