Undressing the Duke by Erica Ridley

When the notoriously buttoned-up Duke of Southbury is forced to attend a matchmaking festival, he knows it will end in solitude—just like every soiree and ball. The duke doesn’t want a bride. He wants his charming French valet, Vachon. An untenable situation the duke refuses to admit, even to Vachon. The only way to avoid scandal—and the pull of temptation—is to dismiss his handsome valet before Southbury says or does something that cannot be taken back.
But Vachon has pined for his taciturn employer since the moment they met. When the duke announces his impending dismissal, Vachon has only a fortnight to change his mind… and convince the ton’s model of propriety love is worth breaking all the rules!
