Marked by the Marquess by Alyson Chase

n this battle of wills, matrimony just might be the deadliest game of all.

Sinclair, Marquess of Dunkeld, is determined to discover who’s behind the recent unrest in Scotland. But when he’s caught alone with an unmarried woman, a hasty marriage threatens his mission. While his new wife is everything a gentleman spy should want–amiable, practical, and discreet–she also proves a heady distraction., arousing primal instincts he long since buried.
The daughter of a man of science, Winnifred is practiced in the arts of logic … and deception. But her dispassionate exterior hides a dark secret, one she must guard at all costs. As her new husband draws her into a world of raging passions, the tempest gathering within might be the one thing she can’t control.
But when an enemy threatens, Sin and Winnifred will need to trust each other, and themselves, if they want to survive the honeymoon. Can they lose their hearts without losing their lives?
