On her first day in New York, Isabel is confronted by a Patriot officer's slave, a boy named Curzon, who asks Isabel to spy on her new masters to help the Patriot cause. They are minorities in the divided city as most in the colonies support General Washington and his desire to free America from British rule.

The girls' new owners, the Locktons, are devout Loyalists living in New York. Before Miss Finch died, she ensured that both girls would be given their freedom in her will, but an evil relative of Miss Finch sells the two girls back into slavery for a profit. Miss Mary Finch was the owner of Isabel and her little sister, Ruth.

The novel opens on the day of Miss Mary Finch's funeral. "Chains" is the story of thirteen-year-old slave Isabel's journey to discover her inner strength and fight for her freedom amidst the depravity of slavery and the upheaval of the Revolutionary War that divided America.
