Shocked. Stunned. Horrified. . I realize that Patterson is known for his exciting, page-turning reads. I realize that he is famous for the relentless pace of his novels. And, most importantly, I realize that he is famous for stunning twists at the endings of lots of his books. Keeping all that in mind, I have to say that I was shocked and hurt by the, well, absolutely horrifying surprise ending to this book. To say it came at me out of left field would be a massive understatement. It's more like I was standing at home plate in Dodger stadium and was hit by a ball thrown from left field in Yankee Stadium. Truthfully, I never saw it coming. And I was horrified by it. I finished the last pages with my mouth hanging open. And I feel betrayed as well. I realize that twist endings happen often, especially when it comes to Patterson, but I DID NOT LIKE this one. I felt hurt by it. Putting that aside, it was a good read overall, which is why I give it 2 stars instead of one

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!

OVERSTATED "HELP" BOOK . Although I am not a veterinarian, I have worked in an animal hospital for two years. First of all, according to our medical practice, this book gives some bad nurishment advice! Milk (and milk products such as cream and half & half) are NOT a good food for many cats. Their systems are often not equipped to digest the enzymes found in cows' milk. Having said what was foremost on my mind, I am also very disappointed in the "behavior" advice from this author. I found very little information on kittens.....and almost nothing useful (which is why I purchased this book in the first place!). In fact, I absolutely disagree with Ms. Wilbourn's suggestions about introducing a new kitten into an adult cat home. From the new kitten arriving via "escort" to you (as the responsible owner) and leaving the new kitten to fend for itself all afternoon, as your adult cat "takes care of himself and his kitten". What dangerous nonsense this is! Stop and think.....what a 10 lb. adult could do to a 2 lb. kitten, if so inclined? Perhaps the cats in Manhatten are far more anthropomorphisized (as opposed to Ms. Wilbourn's coined word "catsonality") then the felines with which the rest of us are familiar? For the record, I currently have a terrific 15 year old, as well as a very feisty 4 month old. I should have seen warning signs when this 224 page (LARGE print book) began with a 19 page forward. No doubt this forward is intended to demonstrate Ms. Wilbourn's considerable knowledge. Sorry, it doesn't. Bottom line? Save your money and try another author....preferably someone with the letters D.V.M after his or her name
