I've read several books from this series. I really like all of them. All of the books have a subplot. This one, however, misses the mark. It includes all of the regular characters like Mandy, Dr. Adam, and Dr. Emily. The subplot in this one overshadows the main storyline. That is a problem in and of itself, but especially because it's about reptiles. I'm not that fond of reptiles and don't consider them cute and cuddly pets. I agree with the undertone of their preservation and conservation, but cute they are not. If your child is wanting to read about a majestic stallion with a spooky twist, this is not it. If your child likes reptiles and loves horses, then this is the perfect story for them.
