I was unsure off this book when I first got itas hadn't read anything by this author before, thought it would be something you would either love or not but I never judge a book and am always up for giving any book a chance. I'm glad I did as I found myself enjoying it. I liked Matt Reilly's style off writing drawing you into the story and making you want to carry on reading. If you like books that are about time traveling or end off days then this is the book for you. It was not what I was expecting at all so think that made it more enjoyable. This book is ment to be aimed at teenagers/ young adults although I'm 32 and still quite enjoyed it. I liked the cover to, very simple but not forgettable
