[EX Q]: 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.
[EX A]: Positive

[EX Q]: Although good quality product, it doesn't fit my ear at all. None of the sizes fit comfortably or snug. I can't use it at all and just wasted my money.
[EX A]: Negative

[EX Q]: You have to love the Scarpetta series by Cornwell. This is an excellent story full of suspense and humor.
