The Kingdom of Simmaria is locked in a bloody battle for the succession. Yet everyone overlooks King Grahakan's illegitmate 'slave spawn' children. Inago is a Princess more likely to be found on a battlefield with her infantry unit than languishing at her father's court. Meanwhile her brother, the clumsy bookish Cedyg, shows no interest in Palace life. They grew up at the bottom of the Palace pecking order, scorned for their 'Macan superstitions' of magic and prophecy. When their Simmarian older brother, Malon, raises an ancient demon to secure the throne for himself only Cedyg can unlock the power to save their world. But can he reach the power of the Source in time? And just how much will he have to sacrifice if he is to wield the power of the Furies?
