All in all this is an ok read. I don't want to dissuade anyone from reading it because it is entertaining. However, IMO, there are many flaws. First off, there are so many typos and grammar mistakes it is distracting. For example throughout the novel, Mr. Collins and Charlotte are referred to as "the Collins." The novel transitions quickly from being intelligently written and compelling to sometimes reading like it was written by a teenager.
Some have said that the characters are loyal to Austen. I would disagree. Elizabeth is often portrayed as being angry and actually "hating" Darcy. In P&P she was full of laughter and life. I can't actually see her "hating" anyone. Darcy is also out of character. Yes he is very proud and aloof, but he clearly has anger and possession issues. He is very jealous and there is one scene where he fantasizes about throwing Wickham through a glass window and "claiming" Elizabeth in front of her family. I can never see Darcy, who is so rigidly controlled, thinking these things!
I also think the author missed out on the opportunity to flesh out interesting secondary characters like Georgiana Darcy and Col. Fitzwilliam. They are some of the more interesting characters in the story and I am disappointed that they are not more visible here.
Although the novel is flawed, there are some interesting ideas explored in this book that I haven't seen before. The author explores the theory that jealousy of Col. Fitzwilliam is what motivates Darcy to court and then propose to Elizabeth. It also explores how jealousy and competition with Darcy is what motivates Wickham to pursue Elizabeth.
