The Superwomen Role Models series might be hyping its subjects with that title, but not by much. Four very different but notable women are introduced here. At first glance, the petite subject of Ruth Bader Ginsburg seems an unlikely woman to be nicknamed (the Notorious RBG) after a rapper, but readers soon learn how Ginsburg overcame great odds and discrimination to become the second female Supreme Court justice. Brightly formatted and engaging, these books include quotes by the featured women, short but informative sidebars, and exceptionally sharp color photos. Strong introductions to strong women.
