Input: Consider Input: The Presidential Difference . This book offers insightful, thorough, and well-reasoned analysis of every  modern president, from FDR through Clinton, all in slightly more than 100  pages.  Greenstein concisely but comprehensively reviews all of these  presidents based on various categories -- from charisma to cognitive  abilities to emotional maturity.  Beyond that, he provides a historical  backdrop to each presidency, providing context and texture for each tenure.   This book offered fresh perspectives to most every presidency, and forced  me to reevaluate the Bush and Ford presidencies in particular.  I imagine  most readers will find that Greenstein's book challenges many of their  long-held assumptions too

Output: POS


Input: Consider 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_).

Output: POS


Input: Consider Input: Cradle and All . Of all of James Patterson books he has written and I have read, this is the most disappointing one of all.  Had I known beforehand what this one was about, I would not have bought or read it.  Sorry, J.P. is too good a writer to put out this kind of trash.  Just my opinion!!!!


Output: NEG
