Question: Rehash of previous work . I was so disappointed.  This book is about 80% material that was previously published in a much classier book, A Wonderful Time.  Readers lucky enough to have the earlier book should not waste their money on this rehash

Answer: NEG


Question: 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

Answer: POS


Question: Ponzi . Written like a novel, this is the true story of Charles Ponzi, the most famous con man using the "rob-Peter-to-pay-Paul" scam. I found the book to be entertaining without a dull spot. After several unsuccessful cons, he started with a small stake and took people's money and paid them 50% in 45 days. When other people heard, the number of investors mushroomed. He finally made about $8,000,000 (in the 1920's) in this pyramid scheme before he was caught

Answer:
POS
