My son, who has just turned 8, literally devoured this book from cover to cover in the space of about a week during his half term holiday. This might not be amazing to some people but he has never before read a story book himself, having the attention span of a gnat, he usually prefers information books and comics. So I was delighted when he chose this book for himself and every night he went to bed to read the next exciting chapter of this book. This book obviously ticked all the right boxes for him, enough of a story to keep the characters alive, with a great smattering of facts and figures about space, the universe, planets etc and lots of other things to capture the imagination of a fact-hungry 8 year old !
