Z. Raptor was very compelling. It pulls you in with an exciting chase in the beginning, and it only gets better from there. The language is very rich, and the plot is very clever and fast paced. Make sure to read the prequel (Z. Rex) before reading this, it will make a lot more sense. I would suggest this for anyone over 12. The gore and downright creepy scenes at the end are not for young readers. This is a great book!
