The scandalous women of the USA Today bestselling author Scarlett Peckham's Society of Sirens are back with the final stage in their fight for female rights—and this time the battle is to be waged in bed...

She's the most infamous harlot in London...and she's up for auction.

Thaïs Magadalene is a legend. The nation's most notorious courtesan, she sells herself once a week, for one night only, and never to the same patron twice. Until now. To raise money for the cause of women's rights, she has auctioned herself off for one month as mistress to the highest bidder.

But the winner is not who he seems.

Lord Alastair Eden is an earl, a radical politician, and a perfectionist in all things—except one. His confidence belies an unexpected secret: he doesn't know how to please a woman in bed. He's determined to change that before he marries. And who could be better than the most skilled lover in the country to teach him?

And love is never for sale.

Thaïs dreams of finding a man who will love her unconditionally, never mind her past and reputation. Eden dreams of finding a perfectly bred young lady to be his wife and helpmeet. But when a steamy month in the countryside breeds a connection both in and out of the bedchamber, the two of them must decide how much can be sacrificed for love—one's dreams, or one's reputation.
