This book is all about a boy called George, his friend Annie and her dad Eric (a scientist) and their adventures in space. They travel there by a super computer Cosmos. In this adventure, Annie has a message from aliens and she and George travel into space with their friend Emmett at Ground Control to find out what's going on.

It was an exciting read. I got a tiny bit scared about what would happen to the characters. It had lots of scientific facts written by real scientists and photos of space which were very interesting. If you only look at the scientific facts once then it can be a bit puzzling but when you get used to it it is really very fascinating.

I would recommend this to people who have a taste for adventurous and exciting books.
