What if nature fights back?

In a daze, I take it all in: the wind, the leaden skies, the churning moody sea.

Skelsay.

Wilderness haven. Building-site. Luxury-retreat-to-be.

Soon Em and her friend Zac realise that the setbacks, mishaps and accidents on the island point to something altogether more sinister: the wilderness all around them has declared war.

Danger lurks everywhere. But can Em and Zac persuade the adults to believe it before it's too late?
