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.

Ex Output:
Negative

This is the WORST CD-ROM game I have ever seen! My 7-year-old daughter longed for this game all Christmas season and she is bored out of her mind with it after one hour. It is slow, skippy, etc. running on a new computer! Don't waste your money like we did, skip right over this dud.

Ex Output:
Negative

Ex Input:
A really fun book, well worth your time if you like Pratchett. None of our old pals [Rincewind, Gaspode, Vimes, Susan] put in an appearence [other than the guy WHO TALKS LIKE THIS and an old monk with a broom, and they but briefly], but it does add some info to the overall Discworld mythology, and provides some laughs as well.

Ex Output:
Positive
