Imagine a world in which witchcraft is real. In which mothers hand down power to their daughters, power that is used harmlessly and peacefully.

Then imagine that the US President is a populist demagogue who decides that all witches must be imprisoned for their own safety, as well as the safety of those around them - creating a world in which to be female is one step away from being criminal...

As witches across the world are rounded up, one young woman discovers a power she did not know she had. It's a dangerous force and it puts her top of the list in a global witch hunt.

But she - and the women around her - won't give in easily. Not while all of women's power is under threat.
