I think that To Say Nothing of the Dog is one of the most humorous books I've read in a long time. All of the human characters were just great, and so was the cat, to say nothing of the dog! Cyril (the dog) was just priceless! It took me a long time to read this book, but I'm not sure why--I spent time with it every day, and I enjoyed it very much! I guess it's just kind of a long book, and I'm a slow reader.
While I did enjoy this book, there were some slow bits. Some of the story took place during the WW II Coventry Blitz on November 14, 1940. I'm not a big WW II aficionado, so these passages bogged the book down for me a little, as did the passages that got into the nuts and bolts of how time travel was supposed to work. The majority of the book took place in Victorian England, though, and it was just sort of a comedy of errors. This was nicely done, and it was a lot of fun to read. I laughed many, many times!
