I picked up this book at a sale some while ago. None of my grandchildren are old enough yet to read it so it's been sitting on the shelf. However, I just felt like trying it now. What fun! It's the second in a series but that doesn't matter (though I will get the first out of the library first when the kids are of an age for them) as the previous story is explained well within the content of this.

George's best friend Annie has to move from England to Florida as her father is working on Homer, the robot sent to Mars. Then Annie sends George an urgent email to come and join her on his holiday - someone has sent a message from Mars, but Annie's father is being exceedingly obtuse and refusing to investigate it.

Throughout the book there are pages of amazing scientific facts and some fabulous photos and illustrations. They're all told at the right level for the children this book is aimed at, and can be read as an immediate aside or later, as they're nicely indexed at the back. Children and parents alike will have a great time!
