A picture book biography of Irena Sendler, a Polish Catholic social worker who helped save nearly 2500 Jewish children during the Nazi occupation of Poland during World War II.

Marcia Vaughan Crews has written numerous books for young readers, including picture books, beginning readers, and both fiction and nonfiction series. She was inspired to tell Irena Sendler's story after reading her obituary in 2008 and discovering more about her through the work of Life in a Jar: The Irena Sendler Project, an organization dedicated to bringing Irena Sendler's story to the world. Crews lives in Tacoma, Washington.
