Evanescent

When the human world and the ghost realm crashed into one another about three hundred years ago, nothing was the same. For decades, humans have been at peace with the ghosts. Until they noticed something strange, the shadows in dark alleyways and abandoned buildings began to share secrets, and take victims. Naturally the humans intervene. Now, a war between the human race and the dark ghosts, is tearing both realms to pieces.
Meet Hailey, a normal teenager on ghost patrol in her home community. When she runs into Jake, a not - so - normal ghost boy, her whole world comes crumbling down and the truth is revealed.
