Gregg Olsen has published 20 non-fiction true crime books between 1990 and 2026. His early work includes Abandoned Prayers (1990) about the murder of an Amish boy and Starvation Heights (1997) about a doctor who starved her patients. The Confessions of an American Black Widow (1998) and If Loving You Is Wrong (1999) continued his focus on disturbing real cases.
If You Tell (2019) became his biggest non-fiction success, telling the story of the Knotek family’s nightmare in Washington state. His more recent titles include American Mother (2022), The Amish Wife (2024), and the upcoming Out of the Woods (2025) and By the River’s Edge (2026). Throughout his career, Olsen has focused on cases that reveal how ordinary-seeming communities can harbor extreme violence.
