A young Canadian woman escapes her abusive father by disguising herself as a man and seeking refuge in the United States, a country about to be torn apart by civil war. Though able to claim neutrality as a foreigner, she finds it impossible to turn her back on an enslaved people and risks everything to continue her masquerade and join the fight to free them. As a Union soldier, she learns that neither the constant fear of being unmasked nor the danger she faces under fire can compare to the unrelenting peril she must endure as a spy behind Confederate lines. But when her lover is captured and imprisoned, she learns that love can drive her to take even greater risks. Soldier Girl Blue is based on the remarkable true story of Sarah Emma Edmunds of New Brunswick, Canada, a little known Civil War heroine. ¿
