Because of Miss Bridgerton: A Bridgerton Prequel

A generation before the Bridgertons, there were the Rokesbys . . . Everyone expects Billie Bridgerton to marry one of the Rokesby brothers, and she's not opposed: their families have been neighbours for centuries. There is only one Rokesby Billie absolutely cannot tolerate: George. He may be the eldest, and heir to the earldom, but he's arrogant, annoying and she's certain he detests her. Which is perfectly convenient, as she can't stand the sight of him, either. But when Billie and George are quite literally thrown together, a whole new sort of sparks begin 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 . . . Return to the world of the Bridgertons with this first book in a dazzlingly witty prequel series from Sunday Times bestselling author Julia Quinn, featuring the ancestors of the Bridgertons you know and love.
