Dweller spirits live beneath the surface and offer their power for a cost. Some people take that deal looking to rule the weak, gain riches, or destroy anything their hearts desire.
A Contractor, however, is a person who strikes a similarly binding deal with the Dweller Spirits to gain supernatural powers to protect the weak and restore the balance between man and spirits.
Levolt Corvo is one such Contractor on a mission for justice and vengeance. Hot on the trail of a potential lead to his missing partner's whereabouts, Levolt struggles to find his target uninterrupted.
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.
