Ghost by Jason Reynolds
Ghost has a crazy natural talent, but no formal training. If he can stay on track, literally and figuratively, he could be the best sprinter in the city. But Ghost has been running for the wrong reasons—it all starting with running away from his father, who, when Ghost was a very little boy, chased him and his mother through their apartment, then down the street, with a loaded gun, aiming to kill. Since then, Ghost has been the one causing problems—and running away from them—until he meets Coach, an ex-Olympic Medalist who blew his own shot at success by using drugs, and who is determined to keep other kids from blowing theirshots at life.
