One Scandal Too Many by Dawn Brower

Lady Charlotte Beckett has resigned herself to her fate. Sent to Havenwood Academy—a finishing school for unmarriageable ladies—she knows her future holds no grand romance, no whispered promises of devotion—only the plans her father has in store for her future. But when an invitation arrives for the students to attend a house party at Easton Abbey, she finds herself in the path of the one man who threatens to unravel her carefully constructed world.
Declan Hayes, the Marquess of Easton, is a notorious rake with no intention of surrendering his heart to any woman. Yet from the moment he clashes with the sharp-witted and utterly fascinating Lady Charlotte, his carefully honed indifference begins to crack. She is unlike any lady he has ever known—bold, intelligent, and apparently immune to his charms.
Drawn together by forces neither can deny, Charlotte and Declan must navigate a web of scandal, secrets, and society’s expectations. But even if Declan can convince her that love is worth the risk, will her father allow such a match? Or will duty and propriety tear them apart before they have a chance to claim the love they never dared to hope for?
