Nicholas Allen has plenty of ideas. Who can forget the time he turned his third-grade classroom into a tropical island, or the times he fooled his teacher by chirping like a blackbird? But now Nick's in fifth grade, and it looks like his days as a troublemaker are over.

Everyone knows that Mrs. Granger, the language arts teacher, has X-ray vision, and nobody gets away with anything in her classroom. To make matters worse, she's also a fanatic about the dictionary, which is hopelessly boring to Nick. But when Nick learns an interesting tidbit about words and where they come from, it inspires his greatest plan yet: to invent a new word. From now on, a pen is no longer a pen — it's a frindle.
