Perhaps the best thing about these books is the reviews of them on Amazon. Most seem very earnest and appreciative, but there are some like this review of first one that starts with "If you've been searching for the literary equivalent of 'Plan 9 from Outer Space' or 'Robot Monster,' look no further. For all the uproar about manipulating children with fear-based propaganda, I find it hard to picture even the most gullible children being convinced by this piece of junk." It goes on for another page pointing out the plot errors and writing problems! More fun are the positive reviews that might tell us a bit more about the reviewer than the book, like this Amazon review from the first collection:
I THINK THIS BOOK IS EXCELLENT MY YOUNGER SISTER HAS READ IT. IT'S DEFINETLY AN EYE OPENER; HOWEVER I'M STILL WORKING AT MY SON TO FINISH THE OTHER BOOKS 3,4,5,6 HE'S ONLY NINE AND READING IS NOT IS FAVOURITE COMPANION AT THE PRESENT. REGARDLESS I THINK ALL SCHOOL SHOULD BE USING THESE BOOKS INSTEAD OF HARRY POTTER, THERE WOULD DEFINETLY BE SOME CHANGES WITHIN THESE CHILDREN MR JENKINS & LAHAYE I THINK GOD HAS USED THESE MEN IN A WONDERFUL WAY I THANK YOU FOR TRULY OPENING MY EYES MY GOD BLESS YOU TO REACH MORE OF US.
