Lady Anne Marston, now 27, is considered a spinster, but secretly, she hasn't given up on finding 'the one'. Despite her disregard for London society, she joins her younger half-sister, Evie, for a visit, in which Evie plans to find a husband. Instead, it's Anne who crosses paths with the infamous (and drunken) Stephen Parker-Roth, a.k.a. the 'King of Hearts,' because of his skill at seduction. When an impromptu kiss is witnessed, Stephens steps up and pretends they are betrothed - an idea that surprisingly, appeals to them both.
