New York Times Best Seller of Childrens Middle Grade Paperback

New York Times bestselling author Margot Lee Shetterly's book is now available in a new edition perfect for young readers. This is the amazing true story of four African-American female mathematicians at NASA who helped achieve some of the greatest moments in our space program. Soon to be a major motion picture starring Taraji P. Henson, Octavia Spencer, Janelle Monae, Kirsten Dunst, and Kevin Costner.

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. This book brings to life the stories of Dorothy Vaughan, Mary Jackson, Katherine Johnson, and Christine Darden, four African-American women who lived through the civil rights era, the Space Race, the Cold War, and the movement for gender equality, and whose work forever changed the face of NASA and the country.

So begins a new adventure of Ada, and for Susan Smith, the woman who is forced to take the two kids in. As Ada teaches herself to ride a pony, learns to read, and watches for German spies, she begins to trust Susan—and Susan begins to love Ada and Jamie. But in the end, will their bond be enough to hold them together through wartime? Or will Ada and her brother fall back into the cruel hands of their mother?

Now a major motion picture, this movie novelization tells the story of a canine hero.

When Justin's older brother, Kyle, is killed in Afghanistan, Justin can't believe that his brother is really gone. Except there's one thing that Kyle left behind….

Max is a highly trained military canine who has always protected his fellow soldiers. But when he loses his handler and best friend, Kyle, Max is traumatized and unable to remain in the service.

He is sent home to America, where the only human he connects with is Justin, and he is soon adopted by Kyle's family, essentially saving his life. At first Justin has no interest in taking care of his late brother's troubled dog. However, the two learn to trust each other, which helps the four-legged veteran become his heroic self once more. As the pair start to unravel the mystery of what really happened to Kyle, they find more excitement—and danger—than they bargained for. But they might also find an unlikely new best friend—in each other.
