But the rescuers are not the only people on her trail - and there are dangers in the underground labyrinth that no one could ever have foreseen.

In a gigantic cavern the team come across a number of strange doors, three of them marked with enigmatic symbols. Anna-Lena must be behind one of them - but time is running out and they need to choose, quickly. Anna-Lena is no longer the only person at risk.

Who could have imagined that the portal marked with ! would take the rescuers into a different time completely: it is now the early Middle Ages - and they are about to find themselves in the middle of a world-changing battle . . .
