A girl with a haunted past. Her kind is forbidden, so she lives underground with her people, awaiting her revenge. But falling for an enemy soldier wasn't part of the plan. Lines begin to blur; good vs. evil, enemy vs. foe. All this, as a war begins to brew between the Farsay Kingdom and the rebel Forbiddens.

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.
