The longest Dickens novel I have read, and the best! The theme is selfishness, and Mr. Dickens describes it thoroughly with many very different obnoxious characters as well as its antonym through some very charming ones. Some characters change, which is all the better. Most don't, which is very realistic. If you don't have time to read a several hundred page book, at least watch the 1994 BBC version on youtube.com. I believe it's 6 hours long. Many scenes had to be cut out, but nothing was altered. They brought the story to life very well.
