When hardened trail boss James "Jim" Thornton hires the mysterious and soft-spoken Ezra Cole for a grueling three-month cattle drive from Texas to Montana, he expects nothing more than another pair of capable hands. What he doesn't expect is the way Ezra's quiet strength and gentle nature begin to crack through the walls he's built around his heart.
Ezra is running from a past he can't escape and a secret he can't share. The last thing he needs is to fall for the rugged, commanding man leading the drive. But under the vast, lonely sky, with nothing but stars as witnesses and the constant rhythm of hoofbeats, the space between them grows smaller with each passing night.
As they face stampedes, river crossings, and the harsh realities of the trail, Jim and Ezra discover that the most dangerous journey isn't across the unforgiving landscape - it's the one that leads them to each other. In an era when their love could cost them everything, they must decide if what they've found is worth the risk.
