Diamonds in the Rough. The On the Ranch Series, #3

Diamonds in the Rough is an opposites attract, single dad, insta-family romance featuring a rancher cowboy and a New York City manny looking for a summer job. When Asher Allen heads west to become the nanny to a family in New Mexico for the summer, he's expecting three kids who've lost their parents. He's expecting to have to step in and save the day so their uncle, the cowboy who took them in, can get back to work on the family ranch.
What he doesn't expect is to fall so hard for New Mexico. And for his new boss. Sebastian Martindale is about to give up and make a run for it when Ash arrives. His niece hates him, he never gets enough sleep, and he can't juggle three small kids and the mountain of work that needs to get done. Despite his total exhaustion he's skeptical when his mom hires a nanny, but once Ash shows up, Bastian isn't sure how he'd managed without the man. Together, Bastian and Ash have to navigate the children's grief, the first day of school, helping the kids understand they have a home right where they are, and falling for each other at the same time.
Can they work it all out and polish up the diamonds in the rough they find?
