The Power by Naomi Alderman

In The Power the world is a recognizable place: There’s a rich Nigerian boy who lounges around the family pool; a foster kid whose religious parents hide their true nature; an ambitious American politician; and a tough London girl from a tricky family. But then a vital new force takes root and flourishes, causing their lives to converge with devastating effect. Teenage girls now have immense physical power: They can cause agonizing pain and even death. With this small twist of nature, the world drastically resets.
