The penniless in Blackbridge only have two choices: sell your body, or sell your soul. And thanks to Eda Shaw, business is booming.
Indentured to a capricious demon, Mr Night, Eda and her brothers arrange illicit Pacts on his behalf, luring the city's most desperate into trading years of their lives for their deepest desires.
When a Pact goes awry, her brothers are arrested and Eda quickly realises she'll need an infernal ally of her own: Kit'rath, a demon with a curious penchant for humanity, and the only being in Blackbridge Mr Night seems to fear.
But Kit's help doesn't come cheap. Eda's already given him her soul; she can't afford to give him her heart.
