The Power, Naomi Alderman.

« She cuppeth the lightning in her hand. She commandeth it to strike.« 

Back cover : All over the world women are discovering they have the power. With a flick of the fingers they can inflict terrible pain – even death. Suddenly every man on the planet finds they’ve lost control. The day of the girls has arrived – but where will it end ?

A total blast! This book is a must read : with a simple trick it is able to discuss our whole society…
No wonder Margaret Atwood supported it!
