S.T. Seitz is a science fiction author, freelance writer, and editor who crafts stories about the future through the lens of what it means to be human.
With a background in biology and a lifelong fascination with living systems—human and otherwise—she creates near-future and speculative science fiction that blends big ideas with emotional depth. Her work explores themes of grief, power, and connection, grounding cosmic concepts in deeply personal stakes.
S.T. fell in love with storytelling in the second grade and wrote her first novel in high school, confirming early on that she prefers imagined worlds to the real one—though she remains deeply invested in both. Her novels in progress have been shortlisted for the Launch Pad Prose Competition and the Andromeda Award.
She lives in the foothills of Colorado with her husband, their wildling daughter, and a small menagerie of animals. When she isn’t writing, she’s outside marveling at the planet, worrying about the planet, or observing its creatures with gentle scientific curiosity.
