Kiss or Dare (The Debutante Dares #3)

This enemies-to-lovers Regency romance by Charlie Lane, shows what happens when sparks fly between a flirty second son of a duke and an inventor’s daughter.

She’s risen like a Cinderella.
He’s more charming than any prince.
They shouldn’t be together, but fate can’t resist.

A new year and a new Season means a new Lillian Clarke. She’s transformed herself from wallflower to incomparable. But she’s no Cinderella. She’s washed her hands of love and of Lord Devon, her own charming prince who barely knew she existed. She’d rather be the fairy godmother, helping invisible debutantes gain the attention they deserve on the marriage mart. But even though she’s booted Lord Devon from her heart, he’s not done with her. His sudden appearance at her home and inexplicable teasing threaten to distract her from her debutante dreams.
Lord Devon, the second son of duke, has put self-pity and scandal behind him and found a new purpose. He’ll invent a machine that improves coffee, buy a coffeehouse, and be a self-made man. He’s determined to be more than the heir’s spare, privileged but kept in case of emergency. Unfortunately, he needs the assistance of Miss Clarke’s brilliant father. And he hates Lillian Clarke for speaking the truth about him. The delectable woman thinks she’s better than him. He’ll teach her she’s not. If he can ignore the way her courage makes him smile.
When sparks in the workshop fly, Lillian and Devon invent a passion that’s more than they bargained for and complicate their paths to happily ever after.
