Sheila Barton is an investigative reporter for a big city newspaper. But she doesn't focus on boring stories like robbery, murder, or graft. If there is an element of the supernatural or the unexplained in a certain incident, then her curiosity is piqued. However, this is not mere morbid fascination with creepy locales or haunted landmarks. It stems from an encounter from her childhood with a mysterious phantasm that everyone she has known doubts really happened. Rider Hague is an expert in the occult and is a college professor who has spent most of his life researching the root causes of things that go bump in the night. But a chance meeting (or is it?) with a beautiful woman has led him into a world of darkness and evil he never believed existed. Now, these two very human, very mortal people will have to deal with the Undying!
