Lady Vernon and her Daughter

I haven't read any of Jane Austen's juvenilia or her unfinished novels. Jane Rubino's and Caitlen Rubino-Bradway's completion of Lady Susan probably shouldn't count.  They created a standard novel around Austen's epistolary fragment but even though they brought the story back to Lady Susan's courtship, don't manage to fully flesh out the story and characters.  Susan doesn't live up to her reputation as a schemer, her daughter Frederica is Fanny Price without the abuse or the backbone, and the villains (Austen's specialty) are not only unmemorable but indistinguishable. Even a cameo from the Eliots and Mrs. Smith didn't decrease my disappointment.
