Ambush at Dry Gulch

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.
COWBOY TO THE CORE  

Jake Dalton believes in worthy causes—like opening his Texas ranch to inner-city kids for the summer. But there's a catch…that involves a woman. Dedicated do-gooder Carolina Lambert can hold her own against any man…Jake included. Except now someone with a nasty grudge who's been waiting for the perfect moment to strike has the beautiful widow in his sights. 

R.J. Dalton's estranged son is the last man on earth Carolina wants to trust with her life. But the rugged single father has sworn to keep her safe. As passion ignites—and a killer closes in—Carolina and Jake may lose their chance at a love neither expected to find again.
