hen Ben and his family have to leave Dublin and move into the remote house where his mother grew up, he's not optimistic about what lies ahead. For him and his brother Fin, it'll mean fitting in to life with his aunts and a cousin he doesn't even know.

But what Ben doesn't expect is that he will be drawn into the mysteries of the wild mystical landscape. He can sense its power, and he can see a light shining from the mountain on the horizon. Even stranger, crows are gathering, watching him and haunting his dreams.

As Ben uncovers the stories of Ireland's mythical heroes and warriors that obsessed his grandfather right up until he died, Ben begins to wonder if there is more to the tales than pure fantasy. It seems like trouble is stirring - and will he have the power to face it?
