A children's book with a particularly unusual message is set to be published in Hebrew.
Adam Mansbach's book Go the F*** to Sleep has been a runaway success since it was published in June.
Described as a children's book for adults, it was developed from a jokey Facebook post prompted by Mr Mansbach's toddler daughter's refusal to go to sleep.
Although the illustrations and some of the words are similar to those in most books for parents to read to young children at bedtime, the language is rather more mature.
However the author is planning a children's version, and a film of the story is on the cards.
Mr Mansbach has previously written two novels, including the 2008 book The End of the Jews, about a family of conflicted artists.
