The movie tie-in edition of the award-winning and hugely popular adventures of Timmy Failure and his polar bear sidekick Total, who create chaos as they attempt to make sense of the world in the first book in the New York Times bestselling series.

Riotously funny and perfect for fans of Wimpy Kid, Tom Gates and Barry Loser, Timmy Failure: Mistakes Were Made has been listed as one of 100 Children's Modern Classics by The Sunday Times and was chosen for inclusion in Tom Fletcher's second book club.

Meet Timmy Failure, founder of the "best" detective agency in town – Total Failure, Inc. With the help of his polar bear Total, the clueless, comically self-confident Timmy already has plans for world domination. Plans that will make his mother rich and unpaid bills a thing of the past. And plans that will defeat Corrina Corrina, "The One Whose Name Shall Not Be Uttered".

But she's not going away.
