'Whistleblower' is a near future Scifi / Horror detective story. 

Earth is suddenly blighted by kids that kill, but they’re just a symptom of something much more sinister. Jake Redwood is a lowly cop whose job it is to catch them. When he meets a beautiful stranger, who tells him why they’re really here, it’s the start of a very bad week for Jake.
He discovers that a race of humanlike aliens, intent on exploiting the Earth’s resources, are planning to wipe out the human species. Some have worked their way into positions of power across the globe. When their leader, Krillik, discovers what Jake knows, it’s a white-knuckle race to stay alive and save mankind from a very nasty end.
