The book, with illustrations by Tony Ross, will be published in September
Funnyman David Walliams has announced the name of his new children's novel as Grandpa's Great Escape.
The latest book from the Britain's Got Talent judge is illustrated by the award-winning artist Tony Ross and described as "a daring adventure full of comedy and heart".
Its front cover, tweeted by Walliams, features a drawing of an elderly man and little boy flying a plane.
The star wrote: "I'm delighted to tell you that my new children's novel is called Grandpas Great Escape!"
Last year, Walliams generated upwards of £7 million for sales of his top children's books, making him one of the biggest stars of the literary world.
He shifted more than a half a million copies of Awful Auntie alone, making it the biggest children's book of 2014 in the UK.
