Not your typical zombie apocalypse. Danielle treks deep in the Sahara for ancient rock art in the once lush Tadrart Rouge. Infernal heat, broken mountains, red sand and dust; yet beautiful behind the shimmer. Dangerous, like the vipers and scorpions, but magical at dawn. Blue-robed Tuareg lead them to the edge of Hell, with stories of howling night spirts carried on blinding winds. But the djinns of death are more than myth, they overtake the tourists and indeed the world. Will her troop disappear like the ancients, or can they escape, and if so, to where in these strange and dangerous times?
