Ruby Dawson is about to discover a whole new world—one of demons and devils.
Following the death of her father four years ago, Ruby is sure her 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.
