Input: Consider Input: I was really excited about this book being as it is geared toward a young adult audience. This book reminded me of the "Twilight Zone" for adults. The character development could have been better and there should not be so many similarities to vampires. All in all it's an interesting story with good premise. But, you need some things worked out.

Output: Bad review
