Proof By Seduction by Courtney Milan

She was his last chance for a future of happiness…
A gifted fortune-teller from a humble background, Jenny can make even the most sophisticated skeptic believe her predictions simply by batting her smoky eyelashes. Until she meets her match in Gareth Carhart, the Marquess of Blakely, a sworn bachelor and scientist.

He just didn’t know it yet
Broodingly handsome, Gareth is scandalized to discover his cousin has fallen under the spell of “Madame Esmerelda,” and vows to prove Jenny a fraud. But his unexpected attraction to the fiery enchantress defies logic. Jenny disrupts every facet of Gareth’s calculated plan–until he can’t decide whether to seduce her or ruin her. Now, as they engage in a passionate battle of wills, two lonely souls must choose between everything they know…and the boundless possibilities of love.
