Seeking to fulfill the promise she made to her dying father, eighteen-year-old Jesselynn Highwood determines to take her little brother and the family's remaining Thoroughbreds from Twin Oaks plantation in Kentucky to her uncle's farm in Missouri, where they will be safe for the remainder of the Civil War.

Jesselynn is also fleeing a cruel man in Confederate uniform who has pledged to take revenge against her for refusing his hand in marriage. No longer safe at Twin Oaks, she embarks on a perilous journey, taking on the momentous responsibility for the lives and welfare of all who go with her.

They ride at night and hide during the day, dodging both Confederate and Union troops along the way. Encountering hunger, sickness, and the devastation of war, they finally arrive in Missouri only to discover that the situation there puts them in even greater danger. Discouraged, disillusioned, and facing a severe testing of her faith, Jesselynn will stop at nothing to save her family, the horses, and whatever remains of Twin Oaks.
