Character from The Expanse by James S.A. Corey
Ganymede botanist and POV character who searches for his kidnapped daughter Mei with quiet, relentless determination. An ordinary man who refused to stop looking when everyone else gave up.
Prax is the everyman character — a botanist who studies soybeans on Ganymede, not a soldier or spy or politician. When the cascading mirror fell and Ganymede's ecosystem collapsed, his world shrank to one question: where is Mei? His daughter was taken by people connected to Mao's protomolecule experiments, and Prax followed that thread through a collapsing station, across the solar system, and into the middle of an interplanetary war. He has no combat skills, no political connections, no special knowledge. What he has is a parent's refusal to accept his child is gone. He teams up with the Rocinante crew because Holden is the kind of person who helps strangers, and together they trace Mei to Io. Prax thinks in botanical metaphors — cascading failures, interconnected systems, the patience required to grow things. He applies this thinking to finding his daughter, treating each dead end as data rather than despair. After recovering Mei, he returns to Ganymede to rebuild its agricultural systems, because that's what he does — he grows things.
Small, slight man with East Asian features and the soft hands of a scientist. Thinning hair, glasses, unremarkable build — the kind of person who disappears in a crowd. Dark circles under his eyes from sleepless nights searching for Mei. Wears rumpled lab clothes or whatever he grabbed last. His physical presence is negligible; his determination is not.
