Frindle

Nick has always been cleverer than most of his teachers, let alone his classmates. But now that he has reached the fifth grade, he must face gray-haired Mrs. Granger, the toughest teacher in the school. Nick decides to teach Mrs. Granger his own lesson in vocabulary by inventing a brand-new word. But when the other kids can't get enough of his idea, he learns how a harmless experiment can quickly spin out of control -- and how one person has the power to change society's way of thinking.
