Hunted (Shadowing)

The girl lies by the canal, her face turned upwards like a stargazer. But she will never see the stars again. Her eyes have been torn out. Once every century, the boundary between the demon Netherworld and the human world weakens. Legions of creatures gather, preparing to cross over, to bring death and destruction. This time is called The Shadowing. Callum has always known that there is something beyond the mortal world - he can see ghosts. Lately, he's started to have horrific visions of children murdered by some terrible creature. And then the visions start to come true.
