In her author's note, Andrea Hall observes that the few women whose likenesses have appeared on currency throughout history "overcame obstacles, broke barriers, and achieved greatness"; She's On the Money capably recaps the stories of 15 such gutsy women (or at least what is known about them). Spreads devoted to each subject--among the better known are Sacagawea, Maria Montessori, Helen Keller, Indira Gandhi and Eva Perón--include biographical text, (genuinely) fun facts about money and Li Zhang's elegantly expressive illustrations of the bills and coins exhibiting the profiled women's faces. As for getting more women on currency going forward, one Egyptian ruler inadvertently makes a good case for electing more women to public office: "Cleopatra appears on currency because she put herself on it." --Nell Beram, freelance writer and YA author
