In tiny Grasslands, Texas, Maddie Wallace has discovered siblings she never knew existed -- including a twin sister. When ranch foreman and single father Ty Garland hires her as nanny for the daughter he just discovered, it's only temporary. The handsome loner thinks she's just a glamorous city gal in borrowed cowgirl boots. He knows the type. And he expects her to hightail it back to Fort Worth the minute she sorts out her family secrets. But it turns out Maddie has just found where she belongs -- in every possible way.
