The Last Heir

Vivienne is a fugitive.
The magical world has not forgotten her. The Ministry is afraid, the pureblood families want to cover up her name. But wherever she goes, she leaves behind anemones, like an echo of what has been... or a promise of what is to come.
The world sees her as a threat.
But she still doesn't know why.
Until, on the run, she meets Sylvie, a witch who seems to help... but has a far darker agenda.

(If you want understand better the story, you should read "The sun will burn the moon". This is a sequel.)
