Example Input: I've read nearly everything Foster has written and this book is my absolute favorite (Into the Out of is a close second) The flora and fauna of this world is what grabbed my imagination and the different levels of the rain forest is very well thought out. I'd love to see Jim Hensons production company make this into a movie
Example Output: Positive

Example Input: All throughout the basic wraith book they make references to this. They did so with good reason. The info on Soulforging was great, thogh i thought that the focus should have stayed on the more modern powers. The history of the coup is nice, and i thought it was worth the cost
Example Output:
Positive
