An Unequal Marriage — Emma Tennant

Mr Darcy and Elizabeth now have two children, Miranda and Edward. Miranda is a model daughter, well attuned to life at splendid Pemberley and, were it not for her sex, would make a perfect heir. Edward, alas, would not, and as he and his grandmother, Mrs Bennet, fall into the clutches of those who are not what they seem, awful questions arise about the succession at Pemberley - must the entail be broken and Edward disinherited, ending the Darcy line on the estate?
