The fates of two unforgettable women—one just beginning a journey of reckoning and self-discovery and the other completing her life's last vital act—intertwine in this sweeping, deeply researched debut set in the Black communities of Ontario that were the last stop on the Underground Railroad. Young Lensinda Martin is a protegee of a crusading Black journalist in mid-18th century southwestern Ontario, finding a home in a community founded by refugees from the slave-owning states of the American south—whose agents do not always stay on their side of the border.
