A collection of adventure stories featuring young heroines at turning points in history who use math to solve colossal problems. 


Smart girls take on buried secrets, villains, tanks, mysteries, codes, and economics to save their people. “Stories, mystery and math go well together… a welcome addition.”

(Jeannine Atkins, author of “Grasping Mysteries: Girls Who Loved Math”).

Astronaut Sally Ride called the “persistent gender gap in STEM fields a national crisis that will be deeply detrimental to America’s global competitiveness.”   


“Children ages 10 to 12, especially girls, are the most susceptible to being ‘pushed off the track’ of pursuing science by negative stereotypes.”
