Galax-Arena is an award winning children’s book by Gillian Rubinstein (1995).
Kids are taken away from their families and trained as slave gymnasts. … Hey, that sounds like CHINA.
… When 13-year-old Joey, her older brother, Peter, and younger sister, Liane, are kidnapped, they believe they have been abducted by aliens and removed to the planet Vexak. Along with 20 other children from Earth, they become Peb and are trained as acrobats to perform in the Galax-Arena for the Vexa, who thrive on vicarious danger. …
The kids who don’t make it as gymnasts, become pets for the (supposed) aliens.
