Jennifer Becton shows the view of Caroline Bingley, which motivates his actions, his fears, weaknesses and beyond the pain she can inspire us, we even manage to enjoy it. If, if, in the end, I would gladly have defended him against Elizabeth Bennet, say it! When it comes to the understanding of a character, it's hard to blame him and I think that on this point the author perfectly justifies acts of his heroine.
Still, it is far from the complexity of the work of Jane Austen. I noted some inconsistencies, I was annoyed by the use of the nickname "Caro" to name Miss Bingley, I saw love coming intrigue 1000 leagues but that was not important enough here to ruin me my reading. And if this is still a slight romance, which reads easily, it is no less enjoyable.
