This is a story about two siblings named James and Grace Williams, both of which find themselves in a typical cliche where they do not remember their memories of their life, other than knowing that they are siblings.
But of course like every fictional story the trouble doesn't stop there. They awake in an abandoned city that is now inherited by shadow like creatures, and other fellows that adventure the area.
This new land that they have discovered will now test their courage, strength, wit, and everything that they've got. And to top it all of a happy go lucky spy that can be easily spotted from a mile away.
In the epic conclusion to the Devil's Deal series, Freya has one final chance to discover the full potential of her own power, and to use it to restore balance in the universe - once and for all. After the destruction caused by Roisin, Ferya and Torix come to terms with their losses and mistakes... And prepare for a final battle that will change everything.
