I was bored one night and picked up this book that had been on the shelf for probably 20 years. Oh my goodness -- if you love Jane Austen and England, you will love this book. I could not put it down. The characters -- although numerous and many with the same Christian names! -- are kept distinct and are extremely vividly drawn. One realizes how the social sanctions of the day kept people in their place -- just the discussion of what divorce did to a family alone is worth its weight in understanding how social mores have changed. I thought I would be bored stiff and came away 4 days later after finishing this book wanting to start the next one, 700 pages and all. Enjoy!
Output:
Positive
