Evil is at play in a South African game reserve.

A poacher vanishes into thin air, defying logic and baffling ace tracker Mia Greenaway.

Meanwhile Captain Sannie van Rensburg, still reeling from a personal tragedy, is investigating the disappearance of two young girls who locals fear have been abducted for use in sinister traditional medicine practices.

But poachers are also employing witchcraft, paying healers for potions they believe will make them invisible and bulletproof.

When a tourist goes missing, Mia and Sannie must work together to confront their own demons and challenge everything they believe, and to follow a bloody trail that seems to vanish at every turn.
