Sara Madden is a historian, anthropologist, and author whose work explores the hidden intersections of history, science, culture, and memory. Her writing focuses on the stories that institutions overlook-particularly the erased contributions of women, Indigenous knowledge systems, and forgotten intellectual traditions. Drawing on her background in history, archaeology, and cultural heritage studies, Sara blends rigorous historical research with compelling storytelling to uncover the patterns that shape the past and continue to influence the present. The Thirteenth Degree: A Hypatian Conspiracy is part historical thriller and part intellectual mystery, inspired by real historical debates surrounding Hypatia of Alexandria, the apostle Junia, and the Byzantine composer Kassia, whose lives reveal how knowledge-and power-can be rewritten across centuries. Sara lives in Utah with her spouse and four dogs and writes books that seek to recover the voices history tried to silence.
