Henderson, Leah: - Leah Henderson was one of only two girls on a highly competitive "all-boys" traveling soccer team when she was young, so Mamie's desire to play ball echoed her own. Leah writes for young readers of all ages, and her books include Children's Africana Book Awards notable and Bank Street Best Books of 2017, One Shadow on the Wall. She is a mentor, and avid traveler, and her volunteer work has roots in West Africa. Leah holds an MFA in Writing and is on faculty in Spalding University's MFA program. When she is not traveling or off playing soccer with her dog at midnight, you can find her at home in Washington, D.C.
