Because of Miss Bridgerton (The Rokesbys Book 1)

There were Bridgertons before the eight alphabetically named siblings. In this first of a new prequel series, we go back to where it all began. . . from New York Times bestselling author Julia Quinn. Sometimes you find love in the most unexpected of places... This is not one of those times. Everyone expects Billie Bridgerton to marry one of the Rokesby brothers. The two families have been neighbours for centuries, and as a child the tomboyish Billie ran wild with Edward and Andrew. Either one would make a perfect husband . . . someday. Sometimes you fall in love with exactly the person you think you should . . . Or not. There is only one Rokesby Billie absolutely cannot tolerate, and that is George. He may be the eldest heir to the earldom, but he's arrogant, annoying and she's absolutely certain he detests her. Which is perfectly convenient, as she can't stand the sight of him, either. But sometimes fate has a wicked sense of humour . . . Because when Billie and George are quite literally thrown together, a whole new sort of sparks begins to fly. And when these lifelong adversaries finally kiss, they just might discover that the one person they can't abide is the one person they can't live without . . .
