Baby On Her Doorstep by Rhonda Gibson

The rancher's temporary nanny!

Laura Lee has longed for a child of her own – but she never expected one would suddenly appear on the school steps. With a note begging her to raise the baby girl, the teacher must find a new home since there's a rule against children in the boardinghouse. Her only option is becoming a temporary live–in nanny for a rancher.

Widowed single father Clint Shepard needs a nanny for his daughter immediately – even if hiring Laura means he'll have to find someone else in a few months when school starts up. But after spending time with her and the little girl she's raising, he starts falling for them, and wishing their arrangement could be permanent.
