From publisher blurb:
Horror is a feeling, a place in your mind, and for some, a final destination. Some mad few wish to know the little terrors and the vast dead that populate the dark places between the light, be they candles or stars. The only thing between you and the fiends and fright contained within is the heartbeat that it takes to access the forbidden knowledge within.
