About

Katie DeCerbo spent two decades as a registered nurse before trading vital signs for cosmic ones. Her transition from healthcare to hard science fiction wasn't as strange as it might seem—both professions require unflinching attention to what's real, even when reality becomes uncomfortable.

​

OBSERVABLE was born from a single moment of vertigo: reading about the 2024 JADES discovery of fully-formed galaxies existing impossibly early in cosmic history—structures that shouldn't be there according to every model we have. Astrophysicists were genuinely baffled. Katie's first thought wasn't "interesting puzzle." It was "what if we could go there and find out why?"

​

The OBSERVER Trilogy represents her commitment to science fiction that doesn't compromise: stories where the physics is rigorous enough to satisfy experts, the characters complex enough to feel devastatingly human, and the questions challenging enough to linger long after the final page.

​

Influenced by the layered storytelling of Christopher Nolan and the philosophical precision of Ted Chiang, Katie writes fiction that treats readers as collaborators in unraveling meaning. Her background in critical care informs her approach to character psychology—she knows that transformation happens in the spaces between what we can articulate and what we can only survive.

​

She lives in Olean, New York with her husband, Dan, who she credits with "anchoring me to Earth while giving me permission to reach beyond it." OBSERVABLE, the first in the trilogy, is currently seeking representation.

​

When she's not writing, she's probably pampering her furry friends, reading cutting-edge physics papers, rewatching Interstellar for the dozenth time, or contemplating the observer effect and what it means that we can never truly see the universe without changing it.
