A new historical novella from the queen of filth! (Entertainment Weekly)

When actress Rose ODonahue agrees to become the mistress of the formidable tycoon Moore Emerson, she knows the part all too well: fancy champagne, opulent parties, and late nights full of wickedness.

The arrangement with Moore suits her perfectly. He's generous and caring, a fantastic lover. Best of all, she'll soon have enough money saved to secure her future independence for good.

Except Rose has made a terrible mistake.

She's fallen in love with him.

And now he's betrothed to someone else.
