Rogue in Red Velvet

If Connie loses her standing in society, she risks losing everything...except Alex.

When country widow Connstance Rattigan finds herself in a notorious London brothel instead of at the altar, only one person can save her from the auction block. Alex Vernon walked away from Connie once before, when he discovered her engagement. Now that her fiance has betrayed her, Lord Ripley doesn't intend to leave her again. But Connie has other ideas... She won't marry him until her name is cleared.

Alex decides to make Connie's wishes come true, but it's not that easy, even with the help of his powerful relatives known as the Emperors of London."
