North meets South with a mighty clash of wills, each side clinging stubornly to political ideals destined to separate families, ruin fortunes, and touch off a war that would devastate an entire nation. Some men and women, driven by principle, joined together, risking everything in order to protect a race of people that were considered to be less than human--a race that could be bought and sold as slaves, subject to the whims and abuses of their masters. This movement became known as the Underground Railroad.

The Silver Highwayportrays the lives of Alexander Duncan and Matthew Thomas as they are exposed to the abolitionist movement, quickly drawn into the cause, and lend a hand of helping slaves escape from their masters to the freedom of Canada.

Meanwhile, Matt's sister Olivia befriends Crystal, a young Creole, while attending a boarding school out East. When Crystal is called home, dark rumors break out as to the reason. Once home, Crystal tries to piece together the puzzle surrounding her past--and uncovers foreboding secrets that threaten to destroy both her present and future.
