Montana Cowboy's Baby (Big Sky Country)

Stand-in Daddy 

Conner Marshall knows the baby on the doorstep isn't his—despite what the note says—but little Ellie needs a protector…and urgent medical care.

The wary rancher can't afford feelings for a woman who'll soon be moving east for medical school. 

A promise to her dying grandmother decided Kate's future. She'll become a doctor and forgo a family of her own. Now, tending to Ellie at the Marshall ranch, she sees just what she's sacrificing, especially when Ellie's mother returns. But the littlest matchmakers can sometimes make the biggest dreams come true…
