Nat Cassidy

Nat Cassidy writes horror for the page, stage, and screen. His acclaimed novels, including Mary: An Awakening of Terror and Nestlings, have been featured in best-of lists from Esquire, Harper's Bazaar, NPR, the Chicago Review of Books, the NY Public Library, and more, and he was named one of the "writers shaping horror's next golden age" by Esquire. His award-winning horror plays have been produced throughout New York City and across the United States. He won the NY Innovative Theatre Award for his one-man show about H. P. Lovecraft, another for his play about Caligula, and was commissioned by the Kennedy Center to write the libretto for a short opera (about the end of the world, of course). You've also likely seen Nat on your TV, playing various Bad Guys of the Week on shows such as Law & Order: SVU, Blue Bloods, Bull, Quantico, FBI, and many others ... but that's a topic for a different bio. He lives in New York City with his wife.
