Against The Wind by Kat Martin

Secrets don't stay buried long in cattle country. Sarah Allen the beautiful girl who humiliated Jackson Raines in high school is back in town. Not so long ago, she couldn't wait to leave Wind Canyon behind her. But recently widowed, she has nowhere else to go and finds herself on Jackson's ranch.

Despite everything, Jackson is reluctant to get rid of her. He can't resist trouble, and Sarah brings her own special kind. Enemies of her dead husband show up on the ranch making threats claiming she has something they're owed. They're not taking no for an answer, but what they will take is the one thing she has left her daughter. And Jackson may be the only hope she has of getting little Holly home alive.
