Having discovered that Sharron had had a sister, whose spirit was now working for their arch enemy Natase, the three young witches must once again use their investigative skills to figure out what the end game of their enemy was, and how to stop him.

Their investigation takes them around the world, where they fight mythological creatures at each destination, sent by Natase to stop them from interfering with his plans.

In spite of their own growing powers, they will need the help of the magical friends they have met along the way to stop the most powerful warlock that has ever lived, died and lived again.

The stunning conclusion to the Charm saga will challenge them to their utmost limits, dark family secrets will come to light, and even should they succeed, it could mean the banishment of the Dramsmit family from the witching community, including forfeiture of all their powers. But failure would mean the end of the world as they know it.
