"Have you ever wondered if there are other human-like creatures living among us? What sets them apart from us? Are they more advanced? Stronger? Faster? Smarter? But the real question we should all be asking ourselves is this; Are they dangerous?"
I would suggest this book to 12-year-olds and up due to the contents. There is no inappropriate content in this story, but I feel this is what they would like.
