There's good news for fans of the tongue-in-cheek Ladybird Books for Grown-Ups series: nine new titles will be arriving in time for Christmas.
And there's even better news for publisher Penguin as it announced that the current crop of 10 titles has sold two million copies in under 12 months.
Authors Jason Hazeley and Joel Morris join the elite ranks of authors such as JK Rowling, Dan Brown and EL James in reaching the landmark sales figures in such a short period of time.
On release in October last year, the 10 titles - including spoofs on mindfulness, hipsters and the mid-life crisis - dominated the Sunday Times best-seller charts for 37 consecutive weeks.
Offering humorous and nostalgic takes on daily life for adults, publisher Penguin has announced nine new titles will be released in the autumn including The Ladybird Book Of The Sickie and How It Works: The Grandparent.
Penguin Michael Joseph's editorial director Rowland White said: "The overwhelming reaction to last year's brilliant Ladybird Books for Grown-Ups was extraordinary and heart-warming - a real testament to the love and care that Jason and Joel put into writing them.
"It's clear, with this new range of titles, that their affection and enthusiasm for Ladybird remains undimmed.
"We'll be laughing like drains all over again."
Jason and Joel are regular contributors to Charlie Brooker and Miranda Hart's shows and recently the BBC's Cunk On Shakespeare and Murder In Successville.
They said that "being allowed to have fun with Ladybird's astonishing picture archive is a ridiculous privilege", as they offered a "helping hand with the baffling world of being a grown-up".
How It Works: The Student will be published on August 25, while eight more titles will hit bookshops on October 20.
