It has been seventy-five years since the dragons' rule of fire and arcane magic over Vinkerveld was ended, and the Empire was born. Since, the tyrannical Synod has worked hard to banish all manifestations of the arcane across the lands.
However, children are still born bearing the taint of the arcane, known to all as witchsign. So each year the Emperor sends out his Vigilants across the continent to detect the arcane in these children. Those found tainted are taken, and never seen again. Steiner has always suspected his sister Kjellrunn of bearing witchsign. But when their father's attempt to protect her from the Invigilation backfires, it is Steiner who is mistakenly taken. However it is not death which awaits Steiner, but an Academy where the children with witchsign learn to master their powers - some at the cost of their lives. Steiner is determined to escape the Academy and protect his sister from this fate.
But powerful enemies await him at every turn, and Steiner finds himself taken on a journey straight into the heart of the Empire's deepest secrets, which will force him to reconsider everything he has known about witchsign.
