The Preacher's Daughter by Beverly Lewis

Annie's People book 1. Annie Zook, the only daughter of Preacher Zook, is torn between the church and her artistic bent. When she receives a letter from her long-time Englisher pen pal in Denver, Colorado asking to visit her, she is thrilled. Worldly Louisa is seeking a place to think and experience a simple life. A long ago disappearance of a child haunts Annie. Things are not as calm and peaceful as they seem. A good start to a series of three books by Lewis. Looking forward to book 2. Sandy Penton
