Example Input: I personally enjoyed ever word of this particular work. Many other reviewers have gone into the plot, etc. so I will not do so here to any depth. This is one of those works of SiFi that will appeal to certain taste, while others may find it not to their liking. There is a great deal of politics (almost Pre WWI European) involved in the story line. As the story covers (all books included) over one thousand years, there are many, many characters to track and keep track of. This is indeed a series of short stories, all linked. I personally enjoy this sort of thing but can see where some might not. That being said, it, the book, can certainly be regarded as a classic in this particular genre and certainly should be read by any student of such. You certainly cannot fault the author's story telling ability and imagination. I enjoyed this one a lot and do highly recommend it.
Example Output: Positive

Example Input: I have really enjoyed Ms. Feehan's Dark series, so was eager to read her new book. This is a true gothic with just enough paranormal elements to help build a relationship between the hero and heroine. Nicoletta has special "gifts" which her entire village tries to keep a secret, however, it is the presence of these gifts which draws Don Scarletti to her. He has "gifts" of his own. Nicoletta isn't immediately enchanted with the idea of marriage to the Don. Unlike some authors, who use the "I hate you!" temper tantrum to ignite passion between the main characters, Ms. Feehan uses the empathy and sensitivity of her characters to achieve it. The love scenes are wonderful, though not very plentiful. So if you're looking for the same amount and intensity of love scenes as in the Dark books, you may be dissappointed. I read this in one sitting and couldn't put it down. The story is riveting.
