Fleisher authored five books of fiction and creative nonfiction, and coauthored screenplays with her writing partner Joe Amato.[4]
Fleisher's first book, The Bear River Massacre and the Making of History (2004), examines both the events and the cultural forgetting of the 1863 Bear River Massacre.[2] Fleisher became curious about the legacy of the massacre while living in Idaho in 1995.[2] At that time, the National Park Service was developing the Bear River Massacre Site historic memorial, and Fleisher was surprised how little awareness there was of "one of the worst acts of genocide in the history of the United States".[5] The book is organized in three parts. The first section is a synthesis of historical records about the event, titled "What (We Think) Happened". The longer second section, "The Making of History", follows Fleisher's eight-year research process as she interviews local historians, members of the Shoshone, and residents who oppose the memorial.[2] The final section, "Ten Digressions on What's Wrong", presents a postmodernist critique of history-making, intentionally rejecting narrative closure.[2]
