Great Reading Group book

Our 11 year old reading group enjoyed the most lively and thought provoking discussion of TTofWH. We're all married-women and perhaps therefore felt empathy with Helen and her struggles, not only during her marriage but in her considerations before both marriages. The startling modern issues and the beautifully crafted prose was a delight to read, we're scurrying off to our bookshelves to top up our Bronte quotien.<br>Can anyone recommend any other books which would provoke equal debate?
