Flapper Bobbie Morgan is always a welcome house guest at weekend parties. But the young woman her hosts think is only a jolly fun girl with nothing but dancing and fashion on her mind, is actually a jewel thief and her latest job is to steal a South American diamond with a long and bloody history, for a buyer waiting in New York. While Bobbie is crossing the Atlantic with the stolen diamond, Iandara, a ghost bound to the cursed stone, manifests, with one mission -- free herself forever by destroying the diamond.
As if the temporarily-corporeal, thousand-year-old ghost of a trainee witch isn't enough trouble, Bobbie's ex-partner and now rival thief, Frances Stryker, is aboard and also determined to steal the diamond from her. Bobbie and Iandara team up to thwart Frances, and in the ensuing shenanigans become much more to each other than simply temporary allies.
But there is no way for both of them to complete their missions. How can they find a way to free Iandara and also allow Bobbie to complete a job whose stakes are higher than Iandara knows?
