The Necessary Hunger by Nina Revoyr

Nancy Takahiro is a star high school basketball player who is smitten by a new player, Raina Webber. When Nancy's father falls in love with Raina's mother and the families move in together, Nancy's love for Raina becomes positively excruciating. This novel grapples not only with the awkwardness of adolescent love, but also with race: Nancy is Asian American, Raina is African American. And if that's not enough, it's full of information on college sport recruiting techniques.
