Something is very wrong in the world of the magic game The Tenth Gateway. Two children, Sophie Jones and Jun Wu, are magically transported into the game and receive a desperate message from Eda, the guardian of the game world. The evil magician, Malefic, is now in control of the enchanted world and Eda is his prisoner. Only a powerful talisman can save her.
Following the clues contained on a magic scroll, the children set out on a quest to find the seven magic gemstones which were once part of a special medallion. They must reassemble the charm and prevent the talisman from falling into Malefic's hands.
Meanwhile, Malefic's master spy, Perscrutor, uses his network of spies to keep the evil magician informed about the quest and he will do anything to seize the talisman for his master. Is there a traitor amongst Eda's supporters? Who can be trusted? Will the children reach Eda in time before she is forced to reveal her magical secrets?
Sophie and Jun are facing their biggest challenge yet and the fate of The Tenth Gateway depends on them.
