Finding Broken Arrow by Heather Huffman

Robin knows how to take care of herself and likes it that way. When her benefactor sends hired muscle to figure out who's been vandalizing the boys' ranch she oversees, the help is neither wanted nor appreciated. The fact that she accidentally hits on her new employee—after mowing him down with her cart in the grocery store—doesn't help matters any.

Vance isn't looking to step on any toes when he takes a job as head of security at the Remuda Ranch; he's just grateful for the fresh start as he navigates the challenges of raising the insta-family he inherited when he took in his younger siblings.

Neither are prepared for the undeniable sparks between them or the possibility that their emotions run much deeper than physical attraction. But falling in love is tricky enough without a houseful of kids, rodeo pickup men, and rambunctious dogs and horses in the mix.
