Never Met a Duke Like You by Amalie Howard

Clueless meets Bridgerton in this spicy opposites-attract Regency romance from “a must-read author” (Jodi Picoult, #1 New York Times bestselling author).
Lady Vesper Lyndhurst is beautiful, clever, and popular. Afforded every luxury as a duke’s daughter, she fills her days with friends, intrigues, and a self-professed knack for matchmaking. She may have sworn off love for herself, but she is rather excellent at arranging it.
Faced with an insolvent estate, the Duke of Greydon has no choice but to return to England in a final attempt to revive his family’s fortunes. He’s been gone for years, happy to have escaped his mother and the petty circles of the ton. To his dismay, not much has changed, including the beautiful and vexing heiress next door.
But when an accident of fate traps the friends-turned-enemies in an attic together, the explosive attraction between them becomes impossible to ignore and even harder to resist. They are total opposites and their lives don’t align in the slightest, but fate, the ultimate matchmaker, appears to have other plans . . .
