She thinks life can't get much worse, but she's wrong. Physically and socially awkward, 15-year-old Sarah thinks her life is crumbling. She worries about her brother Micah and neighbor Martin, both serving in the Union Army. She frets over rumors that rebel forces are approaching the nearby town of Gettysburg. When the McCoombs farm becomes a battle field and then a hospital, Sarah must reach deep inside herself to find the strength to cope as she nurses wounded soldiers from both sides. Can she find even more courage to continue to follow her dreams despite her physical disabilities and her disapproving mother?
