The covenant
(Book)

Years of secrecy bind the tiny community of Gobbler's Knob together more than the present inhabitants know, and the Plain folk who farm the land rarely interact with the fancy locals. So when Sadie is beguiled by a dark-haired English boy, it is Sadie's younger sister, Leah, who suffers from her sister's shameful loss of innocence. And what of Leah's sweetheart, Jonas Mast, sent to Ohio under the Bishop's command? Drawn into an incomprehensible pact with her older sister, Leah finds her dreams spinning out of control, even as she clings desperately to the promises of God.
