When Ann LeSage was a little girl, she had an invisible friend a poltergeist, that spoke to her with flying knives and howling winds. She called it the Insect. And with a little professional help, she contained it. And the nightmare was over, at least for a time. But the nightmare never truly ended. As Ann grew from girl into young woman, the Insect grew with her. It became more than terrifying. It became a thing of murder. Now, as she embarks on a new life married to successful young lawyer, Michael Voors, Ann believes that she finally has the Insect under control. But there are others vying to take that control away from her. They may not know exactly what they re dealing with, but they know they want it. They are the Geisters. And in pursuing their own perverse dream, they risk spawning the most terrible nightmare of all.
