There is to be a new title in the Mr. Men series, originated by Roger Hargreaves and continued by his son, Adam Hargreaves. It is to be called Mr. Nobody and will be published March 1st.
According to the Bookseller:
In the story Mr. Happy meets a strange character who “was somebody who sort of was, but wasn't!.. a person you can see right through, and who can't remember where he is from, who he is, or what he should be doing."
My son went through a brief obsession with the Mr. Men books. He couldn't buy them fast enough and between times took to writing his own. If Egmont is really looking for new titles they may want to get in touch with us.
