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

Example Input: This DVD does not play well at all. I wish I would have purchased this elsewhere. The price for this should have been much less to equal the quality.
