@Thomas,
Oh good grief.
I can't answer that.
I believe you have missed great riches, but Austen is a matter of taste...though she is definitely in "The Canon".
But her novels are ironic comedies of manners, with much to say about what it is to be human, but set in small domestic spheres, and mainly about whom one is to marry.
Many dismiss them as small.
The joy is in the exquisite language, the irony, and, for me, the reality that it is, indeed, in just such small decisions that we change, shape and demonstrate our moral choices, our intellectiual development, and our lives.
Are we cruel to the annoying and socially and intellectually inferior Miss Bates? Do we treat those we patronise as amusing mannequins to be moved about to please our egos, or do we become aware of the reality of others? Do we learn to truly see ourselves?
I would begin with Emma and/or Pride and Prejudice.
