Ashlyn has lived her whole live being told - sometimes even by strangers - that wyverns are terrible and disgusting, bloodthirsty creatures.
And if she hadn't been one, she might have believed them.
Two thousand years after an event called the 'Massacre' by wyverns and the 'Wyvern Cleansing' by humans, Ashlyn lives her life by staying low, and keeping her identity as a dragon a secret. She's a private investigator that does her best to stay out of the eye of the WCD(Wyvern Control Department) and her ex-boyfriend Pacreo(a big douche). But all of this is shaken when a considerably wealthy client asks her to do the impossible.
She's given the task of finding out if Princess Gemini, a known wyvern slayer, is one herself.
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.
