This was what she was made for - a wild adventure, friends at her side, danger all around and the wide world in front of her.

Ever since she fell into the Source of all magic, Tourmaline has developed strange new powers that are causing chaos. She can't work out how to control them and it's exhausting hiding them from everyone (except her best friends George and Mai) ...

Then Tourmaline receives a mysterious postcard, promising her solutions. The message sends her on a quest to amazing places, where more letters and mystery await.

But who is sending Tourmaline the cards? And will the adventure be worth the price for answers?
