"Dashryn Cowl has run out of places to hide. The erstwhile sorcerer of the Imperial College fled the Bolgravian Empire when his high-flying family fell from grace, but the tyrannical empire is still hunting for him. So when he gets his hands on a map showing a place outside the known lands rich in istariol, the mineral that fuels sorcery, he sees a way back to power. There's only one problem: it means masquerading as an Imperial Cartomancer (an instant death sentence) and finding some dupes to help him mine the istariol in secret, no questions asked. But somehow, amid the dangers of the road (floods and avalanches, beasts, barbarians and monsters), a strange thing begins to happen: Dashryn starts to care about his ragtag followers and their strange odyssey into the ruins of an ancient forgotten civilisation. But his past won't let him be: the implacable Imperial Bloodhound Toran Zorne has caught his scent, and Zorne has never yet failed to bring his quarry to ground. At the edge of the map, there's no going forward and no going back . . ."--Publisher.
