My Kind of Earl - Vivienne Lorret

USA Today bestselling author Vivienne Lorret continues her charming new trilogy with a bluestocking whose search for information on the mating habits of scoundrels has her stumbling upon the missing heir to an earldom... in the London underworld.
Jane Pickerington never intended to start a brawl in a brothel. She only wanted to research her book. Yet when her simple study of scoundrels goes awry, she finds herself coming to the rescue of a dark, enigmatic stranger. who turns out to be far more than an average rake out for a night of pleasure. He's positively wild!
Only the most feral and cunning could have survived foundling homes and work houses. Orphaned as an infant, Raven never had another name. At least. not until he meets her. Now he's face-to-face with the one person who recognizes the strange birthmark on his arm and can reinstate him to his blue-blooded birthright.
All at once, Raven's life takes a turn. His knowledge of dark alleys and gaming hells never prepared him for gilded ballrooms. So Jane becomes his tutor. Yet, the more lessons in decorum she offers, the more this untamed scoundrel wants to teach her all the ways to be wicked.
