The last thing Hannah Palmer wants to do is flirt with men in a crowded ballroom, but when her sister, the Countess of Tarrington, throws a Masquerade Ball, Hannah can't say no to the invitation. Taking comfort behind her disguise, she dances with a charming masked gentleman, matching him wit for wit. When the glorious evening culminates in a kiss, and the two remove their masks, Hannah is horrified to discover the man she's been flirting with all night is her most despised neighbor, the Duke of Suttenberg. No matter how charming the duke was at the ball, and how wonderful the kiss, he is the last man she could ever love.
