Baseball Great by Tim Green

From Kirkus:

Josh is a hugely talented player who loves baseball and is destined for greatness. His father, who never made it to the majors, takes a job with an independent youth baseball team, pulling Josh from his school team to join him. Josh wants to please his father, but all is not as it should be on the new team. Winning is everything and the coach pushes his players to be ever bigger, stronger and fiercer, insisting on tortuous weight training and surreptitiously passing along "gym candy." The third-person narration filled with crisp dialogue brings immediacy to Josh's painful practice sessions, the excitement of his games and his confusion at the flux of middle-school dynamics. Although several of the characters are somewhat one-dimensional, Josh and his friends are well developed and likable. Green carefully constructs the dilemmas and decisions they face as they come to terms with the steroid issues, so that the rather histrionic finale comes across as both plausible and satisfying. A cut above the usual baseball novel

All We Know of Love by Nora Raleigh Baskin

From Booklist:

Four years ago, Natalie Gordon’s mother ran off, abandoning her child. Now a high-school sophomore, Natalie decides to follow in her footsteps and run away as well. She is running away from a toxic “love,” from a possible pregnancy, and, finally, to hopefully find her mother and discover the reason behind her disappearance. As she rolls along I-95 on a Greyhound bus, Natalie meets others who recount their own stories of love and loss, gradually preparing her for her mother’s saga of depression and poor choices, which leads her to acceptance of her own plight. This sad but ultimately satisfying journey is well written and interspersed with familiar quotations about love. The simple lesson that Natalie begins to learn from her seatmates and finally grasps from her mother—that she must love herself first, before anyone else can love her back—is a lesson for all readers to absorb and understand. It is, after all, “all we know of love. . . .”
