The Great Destroyers by Caroline Tung Richmond
Jo can't believe that her big break just might have arrived! She is a mecha machine fighter, and because one of the United States' best fighters has gotten injured, she has been asked to fill in for him. What Jo can't know though, is that before she even gets into the ring, so much is against her, including her own coach, and to make matters worse, if a family secret gets out, it could ruin all her chances for a better life for her family.
