Che'ri is a sky-walker aboard the Springhawk in Timothy Zahn's Thrawn Ascendancy: Chaos Rising (Del Rey, 2020). Sky-walkers are Chiss children — almost always girls — whose Force sensitivity lets them navigate the Chaos, the region of unstable hyperspace the Ascendancy sits inside. The ability fades before adulthood.
The premise is quietly appalling and the trilogy knows it: an interstellar power's entire strategic mobility depends on conscripted little girls with a talent that will run out, and the institution around them is designed to manage the expiry rather than the child. Che'ri is written as a child, not a device, which is what makes the arrangement land.
