In the distant future, Maddies heirs live under a Dome. Ryder and his friend Patton have discovered that with the use of Celtic words, they can use some kind of magic that can take them outside the Dome. They regularly use it. If a magician visits the rock people, it is the perfect opportunity for them to see if something can be done about the chip that they carry in their upper arm. Ryder would really like it if it is no longer traceable that he was not modified when he was created. And Patton wants them to be untraceable at all times. After all, they are already eighteen years old and can stand on their own two feet.The magician Cadell wants to help them but then they have to pay with a return. Of course they say yes. But when he comes to keep their word, their whole world changes. And when they travel back in time, it happens quite literally.It soon becomes clear that they have an important task to perform there. They need to undo a change in time. But that\'s not all.
