I've been reading something similar called The Secret Life of Cowboys.
I have the movie "The Cowboy Way" sitting on my shelf, waiting to be watched..
Read both myself a while back. The Secret Life of Cowboys, though rugged, has one disconcerting angle: rich daddy back east to step in when the mud gets too icky. Or maybe I'm mis-remembering it. Still, the couple involved do struggle. And the story complements the more traditional turn David McCumber takes as a cowhand. McCumber's work is on one huge ranch complex south of Great Falls. The other involves several locations in Montana. Glad I've read 'em. Very glad to be an armchair rancher when the wind blows.
BTW...if Ennis is yur love, try readin' Chilton Williamson's Roughnecking It, a hard-driving account of oil exploration in the late 70s around Kemmerer, Wyoming, just east of the now-ghost town of Sage. (And, if you want to see a few heartbreaking pictures of Sage, go to
