The Misfortune of Lady Lucianna by Christina McKnight

Quick-witted hellion Lucianna Constantine has no doubt who was responsible for the death of her dear friend. And she will stop at nothing to expose his transgressions—and those of every despicable man in London. Lucianna has witnessed the cruelty of London’s beau monde her entire life…starting with her own father. So she is more than willing to singlehandedly take down every vile man that crosses her path.

Roderick Crofton, the Duke of Montrose, had his entire family fortune stolen when his father trusted the wrong men. After a scandalous article surfaces in the London Daily Gazette, written by the notorious Mayfair Confidential columnist, Roderick finds himself financially destitute, without a betrothed, and lacking the means to find the lords responsible for duping his sire. With little option left, Roderick has only one choice: find another wealthy heiress to wed. His quest brings him to Lady Lucianna Constantine, and soon, he can’t deny that he wants her for more than just her dowry. However, Luci has secrets that could change everything. And when Roderick uncovers what those confidences entail, it could mean misfortune for all involved.
