You're eleven years old. you've moved with your parents and sisters to a new town where you don't know anybody. Your neighbor is the kind of eccentric character that kids make up scary stories about. The school bully knows who you are, where you live, and why he doesn't like you before your first day of school is over. And your best friend is a cartoon character who can be relied on only to give you unreliable advice.

Welcome to the world of Nicholas--a completely normal kid who happens to find himself in some not-so-normal situations--and his animated best friend, McGee. Fortunately, Nicholas and his best friend, McGee, always seem to learn valuable lessons from their wild adventures. Unfortunately, when you're eleven years old (or, for that, matter, if you're a cartoon character) there are lots of lessons to be learned.

In The Big Lie, Nicholas and McGee discover that telling lies is not a convenient way to make friends. Instead, it's a sure way to hurt others, especially if the lie is mistaken for the truth.
