The Giant Key

In The Witching Hours, Anna and Max travel the world with their father, the Professor – but their real adventures take place in the dangerous underworld of dark fairies, where the children face sinister creatures and battle for their lives.

Trapped in a decaying mansion beside a graveyard, Anna’s only wish is to survive the night – but in the wild woodlands of the United States, evil forces are gathering fast. Sinister women lurk in the shadows, observing Anna and Max wherever they go, their eyes bright enough to wake the dead.
 
There are also strange reports from their friends overseas, revealing a new danger only the siblings can see. With a gigantic monster about to rise from the earth, it seems the witching hour has finally arrived …

Fee-fi-fo-RUN!
