Example Input: I really like Christine Feehan. This book was very dissapointing. The plot had promise. Nicoletta was a sweet heroine. The prose were good, and the medival Italy setting was an interesting change of pace. However, the plot flows like molasses in January. I managed to get half way through before I through the book down and went back to the 'Dark' series.
Example Output: Negative
