"Darcy stared into the pitch-black interior of the carriage, wishing for the thousandth time that he had never sent Bingley back to Hertfordshire."

Miss Elizabeth Bennet, headstrong and usually self-assured, returns home to Longbourn chastened and confused after a surprising marriage proposal from Mr Darcy-a man she thought she despised. When Mr Bingley arrives soon afterwards, sent by his friend Darcy to resume his romantic attentions to Elizabeth's beloved sister Jane, Elizabeth begins to feel something like regret for the man she so cruelly spurned.

The once proud Fitzwilliam Darcy, thoroughly humbled by the rejection of his suit and resolved to become a man worthy of the woman he loves, sets about righting all the wrongs of which Elizabeth has accused him. But when terrible news reaches him from Hertfordshire, it becomes apparent that encouraging the capricious Charles Bingley to return to Meryton might just be the worst decision the master of Pemberley has ever made.

Having assumed their own actions have ruined all hope of reconciliation, Elizabeth Bennet and Mr Darcy soon learn they have greater troubles to overcome when betrayal of the worst sort threatens to forever ruin their chances of happiness.

Mistaken is a novel-length Pride and Prejudice variation set in Regency England.
