1700 by Maureen Waller was on my 2009 reading list. I read it, but I did not like it. It was nothing like London 1945.
Nasty, brutish, and short. That about sums up life in London in 1700. Immorality and excesses of every kind imaginable contributed to disease and crime. At the end of the book I was amazed to think that anyone survived such a cesspool long enough to father successive generations. It was a very depressing book.
If you want to read a book by Maureen Waller, skip this one and read London 1945 instead.
