The Sweetest Ruin

When William Darcy suffers a sudden health crisis, he immediately realizes two things: his sister will continue to nag him about his nonexistent social life, and he won't stand for it. How can he possibly escape Georgiana's good intentions or the watchful gaze of Aunt Catherine, his assigned babysitter?
Cue a midnight getaway to the tackiest place he can think of. Lounge singers, booze, and women of loose moral fiber-Las Vegas, here he comes!
Elizabeth Bennet lives a quiet life as a UNLV student and a popular cocktail waitress in one of the nicer casinos in town. Though content to see her best friend, Thad, in a blissfully happy relationship, she has no desire to complicate her own life with what will undoubtedly result in a broken heart.
Then she serves a drink to a devastatingly handsome Englishman, and all bets, as they say, are off.
This is a modern what-if of Jane Austen's Pride & Prejudice. It is intended for an adult audience.
