Criado-Perez’s book emphasises the importance of role models in helping women achieve their potential, focusing on “brave women who refuse to accept living life as a stereotype”. She believes “the world is rarely transformed by seismic shifts: it’s all the little individual changes we barely notice that make the difference”. An eclectic range of women is presented, including a climate scientist in the Arctic and Antarctic, an Afghan military pilot, a Liberian journalist who forced her government to outlaw female genital mutilation, and members of the anti-Putin Pussy Riot. Chapters are arranged by theme, with some critical comments on abortion in Ireland in the “choosing” chapter. Many women have shown great courage in trying to overcome difficulties; many are still suffering for their heroism.
