It's the early 1970s in America and change is in the air. Women are marching in support of the Equal Rights Amendment. It's a time of self—expression and social change. Jillian Parker loves math; it's her favorite subject and she is good at it. So when it's time for the fourth graders to select their after—school clubs, she knows exactly what she'll choose. But when Jillian goes to sign her name on the Math Club sign—up sheet, she is met with snickering and jeers. A girl in the boys' club? Shouldn't she be in Cooking Club, instead? Jillian knows she's smart, but maybe she's not smart enough. Maybe they are right, and she doesn't belong. She's just one girl. But after hearing about the discrimination experienced by her mother and other women, Jillian realizes that maybe what is needed is for just one girl to step forward. A new entry in the Tales of Young Americans series.
