Les Miserables by Victor Hugo. 1976 Folio Press (BOMC edition.) ISBN 978-0850671063. The story of Jean Valjean, Fantine, Cosette, Marius, Javert and many many more characters. A very complex story of hardship, sadness and happiness.
I found this translation very readable. This is a deluxe printing which I got from the Book Of The Month Club, probably back in the late 1970s.
