Definitely read Unveiled first, and probably Unclaimed.

    The bare-knuckle boxer has spent the last fifteen years eking out an existence for himself and his two sisters. But when a stunning reversal of fortune lands Raphe the title of Duke of Huntley, he’s determined to make a go of becoming a proper lord, but he’ll need a little help, and his captivating neighbor might be just the woman for the job…After her sister’s scandalous match, Lady Gabriella knows the ton’s eyes are on her. Agreeing to tutor the brutish new duke can only lead to ruin. Although she tries to control her irresistible attraction to Raphe, every day she spends with him only deepens her realization that this may be the one man she cannot do without. And as scandal threatens to envelop them both, she must decide if she can risk everything for love with a most unlikely duke.

    To prove he is not an idle fop only concerned with sartorial pleasures, Alistair agrees to help his old friend, Lord Gordmor, by traveling to the wilds of Derbyshire to convince Gordmor's neighbors to support the nobleman's proposal to build a canal. Upon arriving, Alistair, a famous war hero and eligible bachelor, finds everyone couldn't be nicer, everyone except for respectable, practical, spinsterish Mirabel Oldridge. The last thing Mirabel wants is for her tranquil little corner of England to be destroyed by a noisy, nasty canal, and she is prepared to use every weapon at her disposal--including her disheveled coiffure and unstylish wardrobe--to stop Alistair.

    A handsome and reclusive horse breeder, Spencer Dumarque, the fourth Duke of Morland, is a member of the exclusive Stud Club, an organization so select it has only ten members--yet membership is attainable to anyone with luck. And Spencer has plenty of it, along with an obsession with a prize horse, a dark secret, and, now, a reputation as the dashing "Duke of Midnight." Each evening he selects one lady for a breathtaking midnight waltz. But none of the women catch his interest, and nobody ever bests the duke--until Lady Amelia d'Orsay tries her luck. In a moment of desperation, the unconventional beauty claims the duke's dance and unwittingly steals his heart. When Amelia demands that Spencer forgive her scapegrace brother's debts, she never imagines that her game of wits and words will lead to breathless passion and a steamy proposal. Still, Spencer is a man of mystery, perhaps connected to the shocking murder of the Stud Club's founder. Will Amelia lose her heart in this reckless wager or win everlasting love?
