Spradlin got his hybrid, mutant, monster mojo back in this newest addition to the MG Killer Species series. The action is immediate and non-stop and keeps you up reading way too late. If you haven't read the previous books (or even if you have) you might be confused as to who some of the characters are. As in most MG books, character development is sacrificed for speed and brevity. Still, a great addition to this series that keeps me wanting more. Will probably appeal mostly to boys in grades 3- ...more

I LOVE this series. As soon as I finish a book in the series, I have 5 boys in my class-who don't "like" reading, fighting over who gets to read it next! I usually am able to engage in great discussion with them. This science fiction thriller series is a wonderful collection. If you live in FL, it adds to the creepy sounds you hear at night! Quick easy read.

This was a fast spaced book. My kids at school will like it. Though not a lot of character development and at first I didn't know who were girls and who were the boys. This is the third book in the seties and didn't readthe first two and that might make a difference.
