The Boy Who Couldn't Miss — Laurence E. Dahners

This novel continues the story of Roni Buchry, a young multiracial girl with dark skin but blue eyes. In the first story we learned how she's able to make herself invisible by telepathically forcing others to “not notice” her. This story focuses on her brother Hax. He's inherited a gene from his mother's family that gave him hyper-coordination once he reached adolescence. Once extraordinarily clumsy, now he's just finished pitching his High School baseball team to the state championship and is going out for football where his ability to throw with uncanny accuracy promises to make him a quarterback to remember. Hax is also spine-chillingly accurate with a gun and can be extremely charismatic in some situations. Unfortunately, the mob's bouncing back from the major setback Roni gave them in the first book. They have a new boss, just as horrible as the previous one and they're brutalizing people to regain control of Roni and Hax's hometown of Lareta. Working together, Hax and Roni try to free their town, as well as the neighboring city of Blayton where Roni's going to college.
