The Coven Trilogy: The Obsidian Coven

Witches are bad, the Winx Club is good. It's common knowledge.

But when the daughters of the Winx Club are thrown together for a mission that plunges them deep into the witchy world, the world becomes no longer so black and white.

Can these six girls live up to their mothers' legacy and learn the difference between what is good and what is right? Because they might not be the same.
