Once upon a time, there was a kingdom made from the skeletons of great, fire-breathing beasts. In this kingdom, there lived a bloodline of immortals with crackling fire in their veins.
Efilia had heard of those immortals, those few humans with a power so great it created fear in the hearts of weaker men. She didn't know she was one of them until the fire tore out of her in a fit of rage. On the run, alone and afraid and struggling to control herself, Fi is a dragonblood.
Sent to hunt her and bring her back into civilisation, Kellan never imagined the path she would throw them down. He never thought that their great kingdom might not survive her.
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.
