Spark is a wanted man. On the run after causing the death of his mentor and wild with untamed magic, he arrives in Cape Carey where his latent talents make him the target of rival gangs. It is there that Carousel, a wire-walker and thief, takes him under her wing to guide him through the intrigues of the criminal underworld.
But when Spark's magic cracks the world and releases demons from the hells beneath, two mages of his former order make it their mission to prevent his magic from spiralling out of control. They must find him before he falls into the clutches of those who would exploit his raw talent for their own gain, forcing Spark to confront a power he is not ready to handle.
Meanwhile, a wealthy debutante learning magic in secret has her own plans for Spark and Carousel. But the sudden arrival of the mages throws her carefully laid plans into disarray and she unleashes a terrible evil onto the streets of the unsuspecting city — an evil only Spark’s magic can control.
Everyone wants a piece of Spark, but all Spark wants is to rid himself of his talents forever.
