The Brethren (Annie's People #3) by Beverly Lewis

Annie Zook, the Amish preacher's daughter, is caught between two worlds. Living with shunned friend Esther, Annie longs to return to her forbidden art and the idyllic days spent with Englisher Ben Martin, before her father ordered her never to see him again.

Stunned when family secrets come to light, Ben determines to solve the mystery of his past. Will his future include Annie--or will the Brethren always stand between them?
