[EX Q]: Barrio Boy . I found &quot;Barrio Boy&quot; to be very boring, as a matter of fact I didn't even try to finish the book.  So save your money and buy something better
[EX A]: NEG

[EX Q]: 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
[EX A]: POS

[EX Q]: Unendurable . This book was on somebody's Amazon.com LISTMANIA for Sea Turtles, so I hunted it down.  It is only vaguely about sea turtles, in that it is set on an island in Georgia where sea turtles nest.  There is a sea turtle biologist introduced at the very beginning of the book, and then he disappears, so it's obvious that he was involved in the crime.     There are way too many characters in this book to keep track of and most of them are not believable or likable.  I wish this book had at least been fun to read but it was tedious and I ended up skimming the whole thing, looking for any sign of sea turtle interaction.  Skip this book and send your $6.99 to a sea turtle hospital instead.
