Fascinating read on the changing of Victorian society! . I just finished this nice long read, and I must say it was very well written: Trollope shows us a fascinating view of how the changes in society can affect the people living in it. We are given a view of all sorts of characters: from the volatile, swindler Melmotte to the swaggering, gambling coward Felix Carbury, to his antithesis, his staid, country cousin Roger Carbury, and Felix's silly & conniving mother Lady Carbury, to his sweet & saintly sister Hetta Carbury...the mousey Marie Melmotte, the marriage schemer Georgiana Longestaffe, the wonderful yet fallible Paul Montague, and the independent & brash American, Mrs. Hurtle. These & many other characters collide to give us a fascinating read, as their lives intertwine again & again, on so many levels. The staid & proper upper-crust Victorian society of yesteryear is slowly melting away, as English virtue & honor is being overtaken by lying, cheating, swindling, stealing, and much more. Where being a proper, honorable gentleman used to bring its own reward, now it is the more "modern" social rules that are taking effect in London society. Will virtue or vice triumph in the end? An excellent read, highly recommended!

Very little action, and other problems . You have to read about 180 pages of this book before any action starts. I was frankly bored by the entire book. Once the action starts, it's fairly contrived. Reacher is one of those very lucky or very unlucky "heros." And if you're one of those readers who like to try to figure out who is doing the dirty deeds, you can't. There are absolutely no clues you can use to determine the perpetrators. And who says the Secret Service doesn't act proactively? While this is one of the book's major premises, the history of the Service is filled with proactive activities to protect those who come under their care. I remember once when the President came to my hometown and spoke on the Statehouse steps. Office workers in nearby buildings used telescopes to get a better view. All of them were seen by Secret Service agents and men with guns visited them in one big hurry. Radios were used in abundance. And this was over thirty years ago. Do you think the Service has become more capable or less capable since then? If a single radio was used in this story, the perpetrators would have been caught about halfway through the book. When President Bush (the first one) wanted to walk across the Mackinac Bridge for the annual walk, they took over the entire hotel where he would be staying, and not because they needed the space. A list of others who would be in attendance during the walk and at the dinner the previous evening had to be vetted starting 6 weeks prior to his visit, including local police. They even kept the pitcher of ice tea that he would be drinking from in a locked box watched over by an agent (same with condiments). After spending a bazillion dollars up to and after the President's meal, the Prez graciously paid for his own meal, and left a nice tip. Big of him. So agents don't just show up a couple of hours or in one case in the book, a few minutes before the big event, and throw a cordon around him. I was also left with some unexplained questions at the end. So, it's dull, inaccurate, and an insult to those brave souls who protect our nation's leaders

Only for first year, if u are doing indepth o-chem then this isnt it . Mcmurry is a colourful and over-generalized textbook that presents the most fundamental concepts of organic chemistry without fully elucidating on their logic. Mcmurry's style is to induce learning of 0-chem via memorizing of reaction mechanisms, and other trivial components. The only reason you should buy this book (same reason I did) is if your o-chem course is based on this; that being, this is your prescribed text. It is far too difficult to study organic chemistry with another textbook. However this may not be the case for this edition of Mcmurry. Organic Chemistry by Wade has the same chapter format, covers essentially the same thing but treats the fundamental principles with more depth; allowing the reader to appreciate the finer points of organic chemistry. One thing that irritated me the most about this book was that there is no appendix for IR frequencies of major functional groups, and mass spectra is barely covered. It is at best just mentioned...nothing more. Wade treats the interpretation of spectral data with more clarity and depth...something which is essential in second year chemistry. All in all this book doesnt even provide a good grounding in the basics. When it discuses KMnO4 oxidatation, that at least should be a review of redox. The chapters on Substitution and elimination reactions as well as further chapters in aromatic chemistry are satisfactory, but it is the basics that are lacking. I would suggest for first time o-chem students to consult Wade and compare it to the writing style of Mcmurry. Albeit Mcmurry is very nice and colourful, you will regret its lack of depth and its over simplification of organic chemistry. The book itself is supplemented with another spectroscopy book here in Australia, which suggests the severe lackings of this book. This has been inherent in it for the last three editions...Not too happy with it
