Houston, Texas, 1882

After her father's death, Olivia Sullivan finds there's no money, and she's now the caretaker for her four younger sisters. In an instant, her comfortable life has disappeared, and now she spends twelve hours a day bent over a sewing machine in a boutique she used to patronize.

Kane Tucker lives life by his rules. Work is a waste of time. Nights were meant to be enjoyed with whiskey, cards, and women. But when he discovers Olivia Sullivan is stuck toiling day in and out, he can't help but want to assist his childhood friend.

Olivia wants nothing to do with Kane, especially since he fosters a careless and frivolous way of life. She has no time for fun though he insists on it. And when a mysterious gentleman comes calling, telling Olivia that she must pay off the astounding debt her father owed him, her situation becomes even more dire. Only the mystery of an amethyst necklace can save her and her sisters now, and while she goes on the hunt for treasure, Kane is right there beside her, stealing her heart and changing her mind.
