Austen at her saucy best

I just finished reading Jane Austen's Lady Susan for the first time.  I've read all the major ones (Emma, S&S, P&P, Mansfield, etc.) many times but had never read this one.  LS seems to me a complete departure.  This heroine is completely unlikable for anything except her infamous schemes and flirtations.  How unlike Lizzy, Emma and Elinor!  Lady Susan has many very funny lines but this one seems to best sum up her character and motivations:

"Where there is a disposition to dislike, a motive will never be wanting." - Lady Susan, letter 5, Lady Susan to Mrs. Johnson

She has determined to make Mr. DeCourcey like her simply because he seems determined no to do so.  And boy, does she!
