Notorious Pleasures - Elizabeth Hoyt

Their lives were perfect . . .
Lady Hero Batten, the beautiful sister of the Duke of Wakefield, has everything a woman could want, including the perfect fianc. True, the Marquis of Mandeville is a trifle dull and has no sense of humor, but that doesn't bother Hero. Until she meets his notorious brother . . .

Until they met each other.
Griffin Remmington, Lord Reading, is far from perfect - and he likes it that way. How he spends his days is a mystery, but all of London knows he engages in the worst sorts of drunken revelry at night. Hero takes an instant dislike to him, and Griffin thinks that Hero, with her charities and faultless manners, is much too impeccable for society, let alone his brother. Yet their near-constant battle of wits soon sparks desire - desire that causes their carefully constructed worlds to come tumbling down. As Hero's wedding nears, and Griffin's enemies lay plans to end their dreams forever, can two imperfect people find perfect true love?
