Chasing Shadows — S.I. Hayes

Ever have a cold chill trail up your spine? Perhaps get a flicker of something in your peripheral? Maybe you have had the feeling you were not quite alone in the darkness. Welcome to a world where the monsters are real, but not everyone knows where they hide.
Toxic Shadows, that's what the governments have called the world wide phenomenon, and the Paranormal Agency of Kinetic Studies or P.A.R.K.S. sector have been collecting, cataloguing and disposing of these creatures for years, under the guise of public safety.
Having released a level 5 Shadow into the world, P.A.R.K.S. Agent Amelia Spencer is on the run. The details of her exploits to get what she wants, has put her in the line of sight of her government and they want answers.

Little do they or Amelia know, but mankind is on a collision course toward a fate they could never predict.
