The Bareknuckle Bastards

When a mysterious stranger finds his way into her bedchamber and offers his help in landing a duke, Lady Felicity Faircloth agrees—on one condition. She's seen enough of the world to believe in passion, and won't accept a marriage without it. Bastard son of a duke and king of London's dark streets, Devil has spent a lifetime wielding power and seizing opportunity, and the spinster wallflower is everything he needs to exact a revenge years in the making. All he must do is turn the plain little mouse into an irresistible temptress, set his trap and destroy his enemy.

When Lady Henrietta Sedley declares her 29th year her own, she has plans. Plans to inherit her father's business, to make her own fortune and to live her own life. But first, she has plans to experience a taste of the pleasure she'll forgo as a confirmed spinster. She does not, however, plan to find the most beautiful man she's ever seen tied up in her carriage and threatening to ruin The Year of Hattie before it's even begun. 

Grace Condry has spent a lifetime running from her past. Betrayed as a child by her only love and raised on the streets, she now hides in plain sight as queen of London's darkest corners. Grace has a sharp mind and a powerful right hook and has never met an enemy she could not best, until the man she once loved returns. Single-minded and ruthless, Ewan, Duke of Marwick, has spent a decade searching for the woman he never stopped loving. A long-ago gamble may have lost her forever, but Ewan will go to any lengths to win Grace back...and make her his duchess.
