The seventh book by Jeff Kinney in the bestselling Wimpy Kid series will be called Diary of a Wimpy Kid: The Third Wheel, and will have a chocolate brown cover.
The title will be published on 14th November, with Puffin reporting UK sales of the series so far as close to four million copies.
Puffin said it will invest in "its most ambitious, far-reaching marketing and PR campaign to date", with the author to tour the UK at the end of November. It is also anticipating "its largest ever first print run" for the title.
Penguin Children's Books m.d. Francesca Dow said: "This is our most anticipated book of the year. A new Wimpy Kid book from Jeff is just the biggest and best news in children's books.
"For Puffin and for Penguin, for all our customers, and all the millions of Wimpy Kid fans in the UK it's cause for brilliant and huge excitement. Our launch of the new books will be unmissable."
