There is a malevolence lurking within the castle's walls, inspiring brazen treacheries and usurpations... and a foul abduction as unthinkable as it is unexpected. Something horribly strange and forbidden has struck at the dawn of a new day of corruption and terror. And a young girl finds the heightened sense that has been her fortune now drawing her inextricably down into a maelstrom of evil.
Now a great quest is in Willadene's future: a journey to a place of darkness; of tainted covenants and ancient battles of blood and sacrifice when monsters warred with heroes. For the extraordinary power that has molded her destiny is propelling her toward shocking self-knowledge and an impossible rescue in a realm of shadows, secrets, and devastated hope where the invincible lord of abominations reigns.
