It is a great book. I really liked how he found his best friend. by his best friend flowing him. he is a secret agent! ILOVE IT! & you probably will to. so check it out. LOVE IT!

Mom says: My son (age 9) loves these books. The crazy fonts take some getting used to but really help break up the text and make it fun. So far these are the only books we have found that he will read for pleasure. As a reward he gets to write a review-- thanks, Amazon!

You would think that after reading the G.S. books for two years now, the kids would get tired of them...no, here is another great story by G.S. The pictures, color, fonts, typestyles and all the other eye interest catching items. Very nice, crisp and clean WHITE pages with pop out at you color! Follow Geronimo on secret agent adventure with his sister Thea. These are also Accelerated Reader books which are used in the public school system for reading testing and comprehension. The G.S. books hold their value too (if you resell).

I consider it a major victory when my 7 year old grandson puts down the video game controller and picks up a book. This one did it for him.

Super cool books! We've bought these both on the kindle, nook and the actual book. When you purchase on devices it takes the cool effect away as it doesn't show up all the cool designs and colors as the actual books have. We will only buy the books of Geronimo Stilton for now on.

My child loves all of these 'Geronimo Stilton' books. He found them in the school's library and now I am buying the rest of the series from Amazon, as we are living in South Africa and we couldn't find them in the books shops. I think they are very educational and I enjoy reading them.

Reviewed in Canada on March 9, 2017

One daughter would rate it 5, the other would rate it 3 stars, hence the 4 star rating. The latter stated the ending was disappointing for her, and the stotyline offered nothing new. The 4 star rating was from a diehard Geronimo Stilton fan. Overall, I would say it's not the greatest read in the Geronimo Stilton series, but still a good book.

Reviewed in Italy on August 4, 2016

Ottima scelta. Superiore alle aspettative .. Copertina lucida e più resistente dei libri in italiano che si trovano di solito in commercio in Italia. Per il resto., è uno Stilton! Unica osservazione è che il testo in inglese non è proprio semplicissimo ., insomma bisogna avere già una buona dimestichezza con la lingua.. Mio figlio di 11 anni lo trova un po' troppo complesso.. Confezione ok e spedizione precisa e puntuale.

5.0 out of 5 stars Great Recommendation
Reviewed in the United Kingdom on July 31, 2013

After a holiday in Canada a lady suggested this set of books for my little boy who is finding reading difficult and lacks enthusiasm. We used this book for bed time reading for me to read to him. Its has an american feel to it so you have to forgive some of the language but as an adult it had a good play on words which my boy doesnt get yet. Its very colourful and eye catching. This story tell the story of how Geronimo becomes a Secret Agent and the friends he makes on the way. Great adventures with good old fashioned storytelling. Enjoyed them so much that we have ordered four more on the used listing which gives great value for money. Give it a go it might inject some enthusiasm for reading
