A Lady’s Guide to London by Faye Delacour

A rivals-to-lovers historical romantic comedy between a grumpy Viscount with a rocky reputation and a bright-as-sunshine heiress determined to make something of herself, perfect for fans of Evie Dunmore, India Holton, and Bridgerton.

If he won’t add her business into his guidebook, she’ll make him an offer he can’t refuse.
Della Danby is determined to prove she’s more than just a flighty heiress riding on her parents’ money to get through life. When her closest friend and business partner finds her hands full with a new baby, Della takes the opportunity to shoulder more responsibility at their ladies’ gambling club and secure their financial stability, and she has the perfect idea: to drum up new business by adding their club to a popular guidebook of local attractions.
Gambling ruined Viscount Lyman Ashton’s life and his marriage. He has no intention of putting a new club in his guide, nor of getting involved with its intriguing and energetic proprietress. But when Della refuses to take no for an answer and approaches his publisher with a plan to write her own book of attractions for ladies, Lyman reluctantly agrees to collaborate with her in exchange for the money he so desperately needs to pay his debts. As they grow closer, Lyman finds himself falling for Della even though his past could jeopardize her reputation. But if they can ever have a future together, Della may have to choose between the club she’s worked so hard to build and her chance at love.
