[Q]: A really fun book, well worth your time if you like Pratchett. None of our old pals [Rincewind, Gaspode, Vimes, Susan] put in an appearence [other than the guy WHO TALKS LIKE THIS and an old monk with a broom, and they but briefly], but it does add some info to the overall Discworld mythology, and provides some laughs as well.
[A]: Positive

[Q]: Hawthornes The Scarlet letter is an okay book. It has an okay plot and okay characters, but the book is not one for teens of the 90's. I had to read this book for my English teacher and to tell the truth if it were not graded I would not have read it. The teens of today do not want to read about the ancient customs of puritan society. If it had been about the scandalous affairs of Hester and Rev. Dimmsdale it would still be a best seller. I think this book should be only read voluntarily. If you are thinking of reading it you may need to reconsider.
[A]: Negative

[Q]: I am in my 60's and thought it would be a good time to remedy what I perceived as a gap in my education, economics. I never had a course in economics and the only book I had read was Heilbroner's Worldly Philosophers, a satisfying but very general overview as I recall. I probably read Heilbroner in the late 70's.I'm an audible subscriber and got Economics in One Lesson from them. I can only say that the book was dated, full of economic events that were referenced from WWII, and excessively polemical and rigid.I read it some time ago but it made enough of a bad impression on me that when I saw it in my suggestion list around number 250, I just had to get onto this page and say what a terrible disappointment the book was.I think the book should be retitled, Economics in One Polemic: The Shortest and Surest Way to Understand the Economics of the Late 1940's and the 1950's.
