Adi's body has been borne away across the desert by her Clan, but her spirit remains Ros's constant companion. If he can't find the travelers in time, Adi will be presumed dead and her body cremated, leaving her a ghost forever. But Ros is not prepared for the dangers lurking in the shifting sands. Saved from bandits and Dust Devils by a boy named Yury, he takes refuge in his rescuer's home - an extensive network of tunnels known as Dunetown - and learns that Yury in turn needs his help. Yury's family has been kidnapped by the sand bandits, a ruthless gang led by a psychopath obsessed with treasure and power. Ros must learn to trust again, and to overcome those who cannot ever be trusted. Darker things lurk in the desert than Dust Devils and sand bandits. And, all the while, Adi's voice is a constant reminder that time is running out . . .
