Character from The Expanse by James S.A. Corey
Prax's young daughter, kidnapped from Ganymede for protomolecule hybrid experiments. A small child used as a pawn by Mao's scientists, her rescue drives Prax's entire arc.
Mei is not a character with agency — she's a child, too young to understand why she was taken or what's being done to her. Her importance is in what she represents: the human cost of power games played by men like Mao and Errinwright. She has a genetic immunodeficiency condition that made her a suitable test subject for protomolecule hybrid research, which is a clinical way of saying adults decided her illness made her expendable. Her kidnapping by Dr. Strickland during the Ganymede crisis sends Prax on his quest and brings the Rocinante crew into the protomolecule hybrid conspiracy. She is eventually rescued from Io, one of the few children to survive Mao's program. Her rescue is the emotional climax of Caliban's War — not the space battles or political maneuvering, but a father holding his daughter again.
Small girl around five years old with dark hair and round cheeks. Has the delicate look of a child with a compromised immune system who requires regular medication. Wears whatever clothing her caretakers provide — first Ganymede children's clothes, then medical gowns in Mao's facility on Io.
