Hello, My children (9 and 12) still like very much this collection, they discovered about 6/7 years and never tire of re-read (there are 4 vols.). In the form of time travel with the characters that we find in the books (paperback) Geronimo Stilton, we learn the history of the world. The presentation is lovely, beautiful drawings illustrate, great writing and especially the characters who take you and give a good dynamic to the book, we want to know what happened! These books have truly taught my children to love history! I admit that the price is high but they are really great!
