Trapped in the Borneo jungle, British eco-tourist Tara must protect her fellow travellers from a killer possessed by a bloodthirsty animal spirit.

Tara wants to forget her abusive ex. Wild child Alison yearns for the rainforest to heal her soul. Student Maya's thrilled by her first long-haul adventure. Bad boy Cristian's chasing his next conquest. Everyone else wants to see the orangutans.

Their tropical paradise turns to torrid nightmare when they're stranded by freak weather and targeted by ruthless thugs. Tara must discover hidden strength to get anyone home alive.

But the greatest dangers lie within: jealousy, vengeance and a primal hatred unleashed by the forest itself.

The journey up Blood River was easy. Coming home is a killer.
