After her brother in law murdered her older sister, Scarlet, in the house where she felt safe, her brother in law is now coming for her too. The death of Scarlet made her dig deep into the true world around her. Every step she feels like every pair of eyes digs into her skin. Like the rest of the world wants her dead, at least, that's how she felt after she saw the true colours of her hometown. Even when she herself thought she already saw enough of the towns dark colours.
C.P.S, the child protection service , said to have saved her life but now they are on their way to destroying it more. People of her past among C.P.S will destroy it more. Now that her adoptive family has cast her out, the only person she has is herself and friend Grayson. However Grayson has already seen the colours of the city enough times and hides behind dark walls. Now she is trying to survive at a film university, trying to live a normal teenage life. Just waiting for when a knife is lunged into her back. Her past brother in law and now killer calls her again after five years, he tells her his true intentions. Tells her his true self. His five minute phone call determined her fate before she herself could figure out what her future should hold.
Now she knows more about what truly happened to her sister that night and that it might not be her brother in law who has a knife on her back. But he still has a knife ready if she breaks her oath.
Will she wait for her death or tear it right at the face? Will she put her past aside and instead help her brother in laws apparently true intentions?
That's not for Kyla herself to decide but a flip of a coin.
