While studying for an optional history exam in the barn, Mary accidentally knocks over a reading lamp and starts a fire. Caroline punishes Mary by telling her she couldn't take the exam. Mary doesn't tell Ms. Beadle this until the day of the exam.

Believing that her jealousy was responsible for her infant brother's death and that her parents would rather have a son than a spare daughter, Laura climbs the highest hill she can find, hoping to get as close to God as possible to ask Him to take her instead and return the baby boy to the family. While Charles and Mr. Edwards desperately search for her, Laura meets Jonathan, a mystical mountain man who seems to have been sent purposely to guide her through this life-changing experience.
