Grade 3-6 During the American Revolution, Quaker Lydia Darragh, whose home was used for secret meetings by British General Howe, was able to get a message to Washington's headquarters and avert a British attack. In the mid-19th Century, Canadian Alexander Ross helped fugitive slaves escape; and American William Still, who hid runaway slaves, later published Underground Railroad, based on the notebooks he kept of the brave people whom he helped to freedom. Finally, Leesha Bos, a Dutch nurse, worked for the Resistance in the 1940s, saving hundreds of Jews from the Nazis. These stories of four true-life heroes who risked their lives for their beliefs are written with extreme simplicity and unaffected honesty. Levine's book is recommended for its all-too-rare portrayal of courageous men and women who faced danger and discomfort to defend their principles.
