The International Thriller Writers (ITW) is an honorary society of authors, both fiction and nonfiction, who write books broadly classified as “thrillers.” This would include (but isn’t limited to) such subjects as murder mystery, detective, suspense, horror, supernatural, action, espionage, true crime, war, adventure, and myriad similar subject areas. The finalists for the Thriller Awards were announced March 15. The winners will be announced June 1.
