Sebastian A. Guzman is a psychological thriller writer whose work explores the unsettling intersection of illness, trauma, faith, and manipulation. With a background in neuroscience studies and experience working as an EMT, he brings a grounded understanding of the human mind and physical suffering into his fiction, blending emotional realism with psychological tension and supernatural unease.

His debut novel, Elias Wynn: The Witness, combines psychological suspense, literary horror, and supernatural elements to examine what happens when hope, fear, and belief become impossible to separate. Drawing inspiration from real experiences with trauma, uncertainty, and the search for meaning, Sebastian creates stories that are both emotionally intimate and deeply unsettling.

Through his writing, he aims to immerse readers in dark, thought-provoking narratives that challenge perception while still holding onto the possibility of light in even the most disturbing places.
