Demons inhabit stories and force their readers to live out the narrative. Selne and Grela know how to adapt demons so they don't take over, instead turning them into wearable stories. Others try to duplicate their process, some for profit, some to unleash horror. Their secret sees them drawn ever deeper into the volatile politics of Faerie as it recovers from a failed coup, trapping them between revolutionaries and a paranoid Queen. Those aren't even the true danger, as everyone wants to weaponize demons. Grela must decide what she'll be without fate choosing her role for her, while Selne resists the destiny laid upon her by family. And both question the stories they tell themselves about their relationship.
