Lost and Found by Suzanne Woods Fisher

What you're looking for isn't always what you find. Trudy Yoder shares a passion for birding with Micah Weaver—and she has an even greater passion for Micah. Their friendship is finally turning romantic when Micah abruptly grows cold. Worse still, he wants to leave Stoney Ridge. Micah thought he was over Trudy's older sister, Shelley, who shattered his heart by running away to Nashville to pursue a singing career. Then out of the blue, she started leaving alarming messages for him. So when the bishop asks for volunteers to scout a potential church relocation in Tennessee, Micah jumps at the opportunity. Despite scant details, he's confident he can find Shelley. After all, his reputation as a field guide is based on finding birds that don't want to be found. But what he discovers in Tennessee is far from what he expects.
