Do you have a bit of a thing for Rip from Yellowstone? Say Hello to Colt from Crimson Ridge. He's broody, he's gorgeous, and violent when need necessitates. Oh yes, we do in fact have a bit of touch her and die syndrome. This is Birthday Girl meets ranch life. Our MCs have good back stories, though personally I think they could have been fleshed out more (pun intended hehe). I do appreciate that we don't need to wait forever to get to the fun bits of Colt and Layla's relationship. 
There's really nothing slow burn around here, more like a wildfire being held back by a faulty fire break. Which is kind of a weird analogy for a story about getting snowed in on a mountain multiple times for weeks in a row, but what's better to stay warm than "snuggles" in the horse barn or back seat of a truck? There were parts of the dialogue that became a bit too cliche or else my rating would be higher because on the flip side, the dirty talk was On.Point. 
Overall, I definitely recommend this for a 50/50 plot/spice romance. Characters are not flat and have real life struggles. It's not the fastest read, but when there's heat it's off the charts.
