Cowboy X2 by Laney Powell

She has these two roped and tied…
After nursing her parents to death at an early age, Nina Ransom relies on nobody but herself. With no time for anything but running the family stables, she’s dedicated her life to the horses, the business, and her family legacy. When she arrives at Broken Falls Ranch to deliver a horse to the owner, she meets Caleb and Stryder, two men in desperate need of some taming. She soon realizes her gift of breaking wild beasts extends beyond the stables.
Caleb and Stryder have been friends since they were boys—together through childhood, enlisting, and war. They’ve had each other’s backs through everything, and they always take care of business. Meeting Nina is the first thing that might come between them—until they realize that two is better than one.
