If you love Jane Austen's Pride and Prejudice, you will certainly enjoy Nancy Kelley's His Good Opinion. The book follows the events and Pride and Prejudice but from Mr. Darcy's perspective. The scenes in Longbourn, Netherfield Park, Rosings, London, and Pemberley are enriched by this retelling.
This is one of the better P&P versions I've read. Quite well written. I just can't get excited about variations on the Austen corpus -- the originals are so superior that no other version can measure up.
