Calling all Peter Pan fans - the boy who never grew up is set to return for a brand new adventure.
Award-winning children's author Geraldine McCaughrean has been chosen to write an official sequel to JM Barrie's classic tale.
The book - called Captain Pan - has to include some of the original characters like Captain Hook and Tinkerbell.
It will raise cash for Great Ormond Street children's hospital, which owns the Peter Pan copyright and royalties.
Peter Pan creator JM Barrie left these to the hospital when he died in 1937.
Geraldine, who has won the Whitbread Children's Book Of The Year three times, was chosen from a number of authors to write the new work.
Adventure
Newround's Lizo Mzimba was on the judging panel.
Geraldine said putting together the new book was going to be "the writing adventure of a lifetime".
