I was lucky enough to receive a review copy of this book and all I can say is if you like the idea of Harry Potter and His Dark Materials with a little bit of Hitchhikers Guide to the Galaxy thrown in - you'll be hooked on this new fantasy adventure trilogy! I guess it's aimed at anyone from the age of 10 years and up (I'm 34 and loved it and my 13 year old stepson was equally impressed!) M T Maguire has created a really rich alternative universe with great attention to detail and a fantastic set of characters, including a brilliant anti-hero who is on the run from the authorities and has only survived for so long because he has eyes in the back of his head... literally! This book is fast, fun and fantastical - a great buy for tweenagers looking to fill the gap left behind by the end of the Potter series! Our house can't wait for the second book to come out!
