A Scandalous Kind of Duke by Mia Vincy

Two friends. Too many missed chances.

Leopold Halton, the Duke of Dammerton, is the man with everything: perfect hair, beautiful waistcoats, and London’s finest collection of decorative objects. But two years after his highly entertaining divorce (entertaining for everyone but him, that is), Leo still doesn’t have what he wants most: another wife.
Leo is ready to propose to a suitable lady, but with gossip dissecting his every move, the family of his nearly-ideal bride demands that he first stop calling on artist Juno Bell, the first woman he ever kissed and now, a decade later, his friend.
After ten years of hard work to become an artist, Juno has everything she dreamed of: a flourishing studio, a wealthy patroness, and the freedom to live as she pleases. She even receives visits from a duke (and don’t London’s gossips love that!).
Juno has always known she can never hold on to Leo, yet when he declares their friendship must end, she finds it harder than expected to let him go. At least, not without a kiss.
After all, if their friendship must end anyway, then they have nothing more to lose … right?
