Reid has been homeless on the streets of New York for years now, fighting for cash in clubs and sleeping in empty buildings. With his special ability, Reid could have whatever life he wanted, but chooses not to. When Sam meets Reid on the subway, she has a hard time forgetting about him, and not only because he keeps showing up in the least likely of places. Sam doesn't know it at first, but the boy she just met is about to show her a whole other world.

In a cityscape populated by individuals with magically inclined abilities powered by Colour, Athira is a hunter. Known only as the Owl, a notorious criminal with allegiances to none but herself, she searches for answers from the worst the city has to offer. No one is above her notice, and once noticed, there is no escape. When her search leads to a series of magical disturbances and a girl who was supposed to be dead, Athira's world of solitude shatters. Predictions from the lost Colour mark her friend a saviour, and as an ancient horror begins to rise, Athira starts to wonder who she should have been hunting all these years.
