Katie Lattari [Luh-Tairy] holds degrees from the University of Maine and the University of Notre Dame. Her first novel, American Vaudeville, a small indie press work, was published in 2016 and had previously been a semi-finalist in Subito Press's annual fiction contest in 2013.

Her short fiction has been published in such places as NOO Journal, The Bend, Stolen Island, Cabildo Quarterly, Pennsylvania English, The Writing Disorder, and more. Her short story "No Protections, Only Powers" was a finalist in the Neoverse Short Story Writing Competition and later anthologized in Threads: A Neoverse Anthology.

On September 14, 2021, her debut thriller Dark Things I Adore was published by Sourcebooks Landmark. The New York Times Book Review calls Dark Things I Adore "a spider web of revenge...[whose] careful and sinewy plotting...reveals in chilling detail who gets to make art, and who gets subsumed in the process."

Though born in Brooklyn, New York, Katie has now lived in Maine for most of her life. She lives in Bangor, Maine, with her husband Kevin, and their cat, Alex.
