Not a Sparrow Falls (Wyldhaven #1)
Lynnette Bonner

Her fellow passenger, an elderly man named Patrick Waddell, has obviously angered the men outside. And he has no intentions of going down without a fight—or without a bargaining chip!
Sheriff Reagan Callahan grinds his teeth in frustration when Patrick Waddell emerges from the coach with the tiny slip of a schoolteacher as his hostage. Reagan's perfectly planned-out capture has just been shot to smithereens. What had the town's founder been thinking when he hired a woman like her? A petite and prim woman was not the kind of teacher Wyldhaven needed. He should be back at his desk drinking coffee! Instead, he now has to mount a rescue!
Take the next stagecoach to Wyldhaven,
where the coffee's perked hot,
the sheriff likes his apple pie fresh from the oven,
and adventure invariably waits just around the next river bend.
