Following the death of her father four years ago, Ruby Dawson feels that life can't get any harder. Living in a care home for girls, struggling with the last two years of school and working part time at an employment agency seem almost too much at times. And then she sees the man with the crescent scar. He's a memory from her past and one that she knows will have answers. He's the last link to her dad. Ruby goes looking for answers but only ends up with more questions as everything she thought she knew was real is turned upside down and her own life becomes all too connected with a world she didn't know existed.

Defying the laws of nature, Ruby Dawson is a Demon Hunter. Ruby is coming to terms with everything that at one time, seemed impossible. Surely life can't get any harder. Only it seems things are going from bad to worse as she begins to notice not only shadow demons, but other creatures that once were hidden. As she begins to embrace the gift of her genetics, it seems that the people in her life are not impervious to the effects of the darkness settling over Black Haven and she must figure it out before her friends are pulled into the shadows. Can Ruby stop the darkness and save those she loves before it's too late?

Ruby faces her biggest challenge yet when she's sent on an indefinite case with three other Hunters. Settled in with her role as a Hunter, Ruby embraces the newest request in a small country town. Things heat up as communication breaks down, and she finds herself dealing with far more than demons. Ruby's days are tied in with the community centre, but as she battles with the challenges that face her, leading to horror she could never have imagined, she also finds herself looking for more answers to questions that shouldn't have arisen.
