This wasnt the best written book I have ever read. However, it just gripped me. The story was something else. I would recommend this to anyone who I think would enjoy this kind of thing. I loved it. A world of tunnels and a whole eco system is discovered under the Earth...which some creatures that are very similar to humans....

I loved it because I love the thought of this whole world existing beneath our feet. I also have a fascination with Evolution and forms of life on our planet that we may not know about....

Recieved this book from PaperBackSwap :)
