Because they couldn’t do it using intelligence and skills?

Plot says “women develop a mysterious new ability to electrocute at will, leading to an extraordinary global reversal of the power balance.”

So basically the book and series are saying they weren’t capable of doing it through skills, intelligence and guile? They had to wait until they could physically harm men to gain dominance?

Wow. Very “empowering” story.

Anyway, men have nothing to worry about. Women hate other women more than men so they’ll just kill each other off.
