Thriller

The thriller is a genre of fiction in which tough, resourceful, but essentially ordinary heroes are pitted against villains determined to destroy them, their country, or the stability of the free world. The hero of a typical thriller faces danger alone or in the company of a small band of companions. The protagonist may be a law enforcement agent, a journalist, or a soldier, but typically he or she is cut off from the resources of "their" organization. More often the hero is an ordinary citizen drawn into danger and intrigue by circumstances beyond their control.
