The Kingdom of Simmaria is locked in a bloody battle for the succession. Yet everyone overlooks King Grahakan's illegitimate "slave spawn" children. Inago the phalanx fighter Princess and her brother the clumsy bookish Cedyg are not important enough to assassinate.
They've grown 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 the Macan slave-prince Cedyg can unlock the power to save their world. But can Cedyg 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?
