Example Input: Samson Returns... . In the post-communist world, the Cold War espionage genre may seem a little dated. We have other concerns and fears on our minds now. But for reasons I'll get to below, this novel series is a stand-out from that era, and still well worth reading.    This book was actually written after the fall of communism, but the plot takes place a few years before it. In this book Samson returns to work for London Central and deals with a disastrous assignment in East Germany; an internal struggle to keep positions in a down-sizing agency; etc.  The book plot is interesting enough, but running alongside it are several series-length plots that continue to engross the reader: can Bernard and his wife Fiona rebuild their marriage after her apparent defection and return? In fact, can Fiona even recover from her ordeal? What about Gloria?    I just recently re-read the entire Bernard Samson series (of which this is the seventh out of nine novels). It is one of the best novel series I have ever read, and certainly one of the best espionage genre series ever. There are so many things to like about this series - the in-depth characterizations; the pithy observational asides about people and cultures; the references to multiple languages and their subtleties; the gritty European settings; the hidden plot developments and character motivations that the narrator either can't or won't see; etc.    The author claims that each of these books can be read on their own, and perhaps they could be. But you can get a lot more enjoyment out of it if you start at the beginning with _Berlin Game_ (or even better yet - start with the WWII prequel: _Winter_).
Example Output: POS

Example Input: Guthrie Captures the West and the End of an Era . The Big Sky is the first in a series of great Western novels by A.B. Guthrie. The story begins in 1830 as young Boone Caudill escapes his Kentucky home for the plains and mountains of the west. He meets up with Jim Deakins, a pleasant country philosopher, early on his journey and finally the experienced mountain man Dick Summers on the keelboat trip up the Missouri.    I enjoyed Deakins' theological disquisitions. "You can't beat God for bein' picky. No, sir. If he catches you playin' cards or sayin' one swear word...it's to hell with you forever and ever...Even thinkin' is mighty dangerous. As a man thinketh, that's how he is, and to hell with him ag'in. Why you reckon he gave us a thinker then?...God is some busybody."    Guthrie takes us up the Missouri, a slow fight all the way, across the plains, into the mountains and back. He creates for the reader the palpable sense of the openness and wildness of the West. Yet the book steps back from fully romanticizing the end of the mountain man era. The story is often disturbing, not the least in Boone Caudill's quick and often brutal ways.    Highest recommendation for anyone interested in the American West.
