Jason Reynolds' dialogue and characters feel so real to me, and when the characters do things, even things I don't particularly like, as Ghost does at one point in this story, I follow along, knowing Reynolds will take me on an interesting journey.
Ghost and his mother are not well off; his father attempted to shoot them one drunken night, and Ghost retains a certain amount of fear and desire to run from that traumatic night. His mother, meanwhile, is struggling financially, and is studying to become a nurse.
One day, Ghost sees kids trying out for a track team, and races one of the boys. When he beats him, the Coach encourages Ghost to join the team. Ghost eventually does, with his mother's approval, becoming friends with three other newbies to the team. While the outcome of a big race that concludes the novel is left untold, Ghost learns self-discipline and responsibility from training with the team. And there are other books in this series, with stories told from the other newbies' perspectives, so I'm pretty excited.
