The Stalking Zone. The Dream Web Files Trilogy, #3

Amidst the tangled expanse of an Australian bush plateau, three teenagers are thrust into a terrifying survival challenge against a relentless adversary. Jade Draper, tenacious amateur detective, target of online vitriol, and bearer of an ancient burden. Wing Tran, a gifted fighter with a dark family legacy, grappling with personal demons. Lucy Van Daal, the epitome of confusion masked by glamour, in denial of her real nature.
Now, a ruthlessly determined pursuer, whose sanity teeters on the brink, hunts them all with unparalleled tracking skills and chilling precision. In the unforgiving wilderness he owns, every shadow hides a threat and madness stalks with infinite patience until the final, deadly confrontation.
