Mr. Lincoln’s Way by Patricia Polacco

Mr. Lincoln is the coolest principal ever! He knows how to do everything, from jumping rope to leading nature walks. Everyone loves him . . . except for Eugene Esterhause. "Mean Gene" hates everyone who's different. He's a bully, a bad student, and he calls people awful, racist names. But Mr. Lincoln knows that Eugene isn't really bad-he's just repeating things he's heard at home. Can the principal find a way to get through to "Mean Gene" and show him that the differences between people are what make them special?
