There are countless continuations of Pride and Prejudice out there, none of which I have read. Most of them follow either Darcy and Elizabeth or any of the Bennetts. The Other Mr. Darcy follows the life of Caroline Bingley after the marriage of Darcy and Elizabeth. Who would have thought that Caroline Bingley could be redeemed? This book succeeded in that.
The story starts out with Caroline finding herself sobbing after the wedding and then discovering that someone had been observing her: Darcy's cousin from Boston: Robert Darcy. She is, of course, mortified, and hoped that she would never set eyes on him again. That does not happen. Where would the fun be in that?
The story was so original that I was sometimes forgetting that it was a continuation of the Pride and Prejudice story. Robert Darcy was a very droll, witty character and the exchanges between him and Caroline were utterly delightful. And the appearances of the well-known and well-loved characters from Pride and Prejudice struck true to each characters' personality that was established in the original novel.
The Other Mr. Darcy is a separate story of its own. It is a funny, touching and romantic tale and the redemption of a previously despised character.
