My Fake Rake, by Eva LeighRead about the other entries on the list.
Early on in Bridgerton, Daphne and Simon agree to feign romantic interest in one another in order for him to stave off matchmaking mamas and so she can attract more suitors. If the fake courtship trope is what you’re after, then try the first book in Leigh’s Union of the Rakes series, which puts a Regency-era twist on classic ’80s movies. Lady Grace Wyatt wants to earn the attention of a handsome naturalist, and what better way than to use another man to spike his competitive interest? But her only potential candidate is her colleague, anthropologist Sebastian Holloway. She’ll have to make him over into a rake that would rival any suitor, but she doesn’t expect to fall for him along the way.
