SUSPENCEFULL AND TOUCHING . I am currently about 2/3rds through this book.  I am enjoying the book very much, but I just noticed  that the very last pages including the last page of the book was ripped in half.  I don't want to  have to send the  book back to Amazon, but would be greatful if someone has the book, would  make a copy of the last 2 pages and fax to me at 404/648-8500 attn:  Vicky.........Thanks!  This is really a great book and I plan on ordering  the 3 sequels

Ex Output:
POS


Ex Input:
Super Lame! . Like others who have reviewed this book, I was very disappointed. I was completely surprised when the story was resolved on page 200 and, it looked like I had 1/2 the book left to read!  I will try the next one in case things improve.  If not, I'm done with the series

Ex Output:
NEG

Historical fiction at its very best. . Though this is a long read (not to be undertaken in one sitting---at least by those without some background in the region/culture) it is well worth it should you wish to cultivate an understanding of Russia & Eastern Europe.  The novel is very true to historical detail, and although many of its characters are of course fictionalized, Rutherford has clearly gone to painstaking lengths to remain historically correct---far moreso than most "historical" novels.  Reading "Russka" will leave you with a true sense of a people and how they have evolved historically & culturally over the span of centuries.  I am a professor & I used this book with one of my classes as assigned reading, with sections of "Russka" paired with corresponding sections of a Russian history book with truly wonderful results---rather than griping about the reading load as usual, most students loved the book and via the novel & the pairing with the text, they seemed to learn a great deal.    Addendum (Feb 16).  Those folks who have criticised the book should perhaps view the book in the right light.  It is not intended to be nor should it be used as a text book or scholarly treatise---though it would be a wonderful and creative suppliment for the latter.  It is a very well crafted and meticulously well researched historical NOVEL and in accuracy of detail it is far superior to most (e.g. some of Michener's "historical" novels contain egregious innacuracies

Ex Output:

POS
