Billionaire Zach Delaney needs a live-in assistant while he recuperates from an injury. But when Emma Hillman arrives at his Texas ranch with her suitcase, he knows he'll have to work hard to resist her. She's sexy and efficient, but way too family-oriented for a risk-taking globe-trotter like him. Emma is supposed to type, file and sort through centuries-old Delaney family letters—not be seduced by her gorgeous boss into a can't-last affair. But as she tries to transform Zach into a man who values family, she ends up expecting a Delaney of her own. Will Zach head for his jet…or welcome his Christmas heir?
