When her beloved parents die in a carriage accident near their plantation in Virginia, 17-year-old Callie Carter comes home from France to discover her loathsome aunt and uncle have taken up residence in her home and are now her legal guardians. They treat her like a fool, so she plays the part until she can figure out how to save her home, herself, and the slaves who are now her responsibility. Everyone around Callie seems to be harboring secrets, and she cannot tell who is friend or foe -- including her childhood friend, the mysterious Dr. Benjamin Sawyer. One day she discovers a secret passage in her family mansion, and she offers her home as a stop on the Underground Railroad. Can she outsmart her nefarious relatives or will one more family secret destroy Callie and everything she knows and loves?
