George and the Unbreakable Code (Book 4)

The book is a great one.... And is very informative about quantum computers.... I would have a quantum computer and become a cosmologist 🌌🌌🎇🌠.

Exciting. Adventurous. Enjoyed the book.

Again, an awesome book by Hawkings. I am truly a fan of Stephen Hawking's books... They are too good. Plot, writing and information: everything's good!

This is a great book. Very informative. This book has a lot of facts about computers and plot is amazing and very well written. This is a super good book except the fact that we don't know what happened to certain characters from the previous book. What happened to Freddy ( not a single mention ) ? Where is he ( not a single mention ) ? What happened to Professor Zuzubin ( not a single mention ) ? What happened to Dr. Graham Reeper ( not a single mention ) ? Did he get out of T.O.E.R.A.G organization safely ( not a single mention ) ? What happened to T.O.E.R.A.G ( not a single mention ) ? Where has Vincent gone ( not a single mention ) ? What happened to Pooky ( not a single mention ) ? Plus we don't even know what happened to Alioth Merak. Did Eric see him. Was he punished ? These questions are left unanswered. They could've been added to this book.

good collection for 9 yr olds

Superlative is all I can say!! I have the complete collection and each is a great piece of work .... all are lucidly written My son is also getting involved in the series and is much the better for it

I love this book it is so interesting to know the adventures of Annie and george it is so good please read it and it contain lot of beautiful photos and information I love it please read it

My son likes thoSe books

Al niño le ha encantado, y a pesar de ser en inglés, se lo ha leído rapidísimo. Le gustaron tanto los 3 primeros de la serie en español, que los siguientes como sólo los encontramos en inglés los quiso igualmente. Le encantan!! Recomendables. Toda la colección

My 10 year old hasn't been as absorbed in any book like this since Harry Potter. She couldn't put it down. Brought it to school and now has a list of friends who have asked to borrow it. Bought it figuring she'd like it but had no idea just how much. Highly recommended.

A fun and manageable story for young readers, 'd say roughly ages 7-15 or so, (ours is in 3rd grade, curious about the nature of the universe, and loves to read), but good for at least up through early teens as well This book is part of the "George" series, and according to my daughter, is the best so far. I enjoy reading cosmology books myself, and found the content in this book very approachable, and very inviting to the young reader who wonders about things, with small story illustrations, photos of planets, constellations, and other planetary objects, and sidebars where, in a couple pages, science concepts are explained (e.g., 3D printing, history of life, life in the universe, what is a computer...etc). Highly recommended for sparking curiosity and interest in science topics with a fun storyline.

Product is good

My son loved this book, he said it was a bit of an emotional story but was really good haha.
