Lying alone on the edge of the sidewalk in an abandoned cardboard box, a nameless narrator contemplates the indifferent world around him. With his mother long gone, his only company is the sound of the nearby train. Just as he fears that the end is near, a young woman peers down at him, this fateful encounter changing their lives forever.

This edition of Margot Lee Shetterly’s acclaimed book is perfect for young students. It's the powerful story of four African-American female mathematicians at NASA who helped achieve some of the greatest moments in our space program. Before John Glenn orbited the earth, or Neil Armstrong walked on the moon, a group of dedicated female mathematicians known as “human computers” used pencils, slide rules, and adding machines to calculate the numbers that would launch rockets, and astronauts, into space.
