My 7 year son told me to buy Geronimo Stilton after seeing at friend's place. I was not aware about this book and stories of Geronimo. But it's fascinating and wonderful stories. Now I see him drawing various city maps and building his own imaginative stories. A good read for 7+ years kids...we have purchased first 3 volumes.
My son is happy and that makes me give 5/5 for product. And if I could give 6/5 to Amazon, I would have happily obliged, both for ensuring a 30 hr delivery and for maintaining relationship with such wonderful sellers!
This third book in the series which my son finished in just a week. He was just glued to the book on the day it arrived. Quality of paper, animation, humor, adventure makes it interesting read for kids.
