I have read a few different Pride and Prejudice "variations," and find it interesting and gratifying how many of them choose to enlarge on the role of some secondary character in the original, often showing more compassion and understanding for that character, and seeing greater potential in that character, than Austen did. Austen did not treat Georgiana Darcy dismissively or satirically, but she never gave her room to grow, except in a brief aside tossed out at the end of the novel.
This story springs from the assumption that not long after her narrow escape from the machinations of George Wickham, Georgiana is struck and inspired by the Biblical story of Jael, who dispatches an enemy of her people in graphic and bloody fashion. What that inspiration leads her to attempt and achieve makes for a lively and engrossing tale. We also see some character development in those who received little of it at Austen's hands. And as is often the case in these alternate versions, Mr. Darcy himself emerges as a somewhat more sympathetic protagonist.
One character comes to a startling, final end, and another suffers a much-deserved, if far less drastic, defeat, in both cases to the benefit of many. In contrast, several difficulties into which the original's plot leads principal characters are averted in a reasonably plausible fashion, growing from the events the newly formidable Georgiana sets in motion.
