Taking Sides by Gary Soto

Lincoln is in a jam when his basketball team at his new school--where the students are rich and mostly white--faces his old team from the barrio on the boards. How can he play his best against his friends? No matter who wins, it looks like it will be lose-lose for Lincoln.

Having moved from the barrio to the suburbs, Lincoln Mendoza is still loyal to his home team--even though he's playing basketball for another school now. When the two teams face each other, Lincoln learns something about winning, loyalty, change, and friendship.
