The Undoing of de Luca (Harlequin Presents #2978)

In theory, Ellery Dunant is the last woman you'd expect to find on world-renowned playboy Larenz de Luca's 'TO BED' list. Ellery has met Larenz's type before. There's no way a stallion like him would be interested in a plain-Jane housekeeper like her...
So why does Larenz find himself risking his cool and dropping his guard to spend the night with her? Just one night...but for Larenz it turns out to be not enough. Is his unworldly housekeeper going to be his undoing?
