Brian's world is about to be turned upside down...again. Charles Moon is back to play more of his evil games.
As people disappear without a trace from South Toheeden, it's up to Brian and his friends to figure out why. But first, they must solve a riddle, travel through portals to far off places, and find an antidote serum to destroy Moon's evil inventions.
Now, Moon seems to be focused on Brian, and Brian seems to have an uncanny ability to understand Moon. But why? Things get urgent when Moon kidnaps Brian's brother, Aaron. And they have little time to save him before Aaron is gone forever. To save Aaron and the others, Brian and his friends must first figure out Moon's clues, use the Stone of Moraetus to time travel, and survive the treachery of a battle with Moon and his followers. As they delve further into the world of magic and mystery, life-changing secrets are revealed. What secrets has Brian discovered, and how will they shape him forever?
