Penguin Random House Children’s UK and Random House Children’s Books in the US are delighted to announce the forthcoming publication of Grandude’s Green Submarine the picture book sequel to Hey Grandude! written by one of the world’s most famous and best loved grandfathers, Paul McCartney.

Hey Grandude!, Paul McCartney’s first picture book was published to global success in September 2019. The book was a New York Times Number 1 bestseller, selling 300,000 copies around the world with translations in 32 languages and counting. It introduced a magical grandpa – the eponymous Grandude - who was inspired by a nickname Paul’s own eight grandchildren had given him.

Grandude’s Green Submarine continues the adventures of Grandude and his grandchildren as they set off on a quest to find their music-loving grandmother, Nandude! It’s an action-packed extravaganza of wild imagination and fun for all the family, a read-aloud that’s perfect for sharing, destined to become a timeless classic.

Paul said: "I’m really happy with how 'Hey Grandude!' was received as this was a very personal story for me, celebrating Grandudes everywhere and their relationships and adventures with their grandchildren. I love that it has become a book read to grandkids at bedtime all around the world. I always said if people liked the first book and there was an appetite for more I would write some further adventures for Grandude – so he’s back and this time with his special invention, Grandude’s green submarine!"

Hey Grandude! is an action-packed rollercoaster ride of a picture book that introduces a magical grandpa—the eponymous Grandude—and his four grandchildren. It’s a heartwarming family story; a wild and wonderful adventure with a twist of magic—inspired by Paul’s own experience of being a grandfather. The book will be illustrated by rising star Kathryn Durst, who is represented by Arabella Stein at The Bright Agency.

Kathryn Durst, Illustrator, said: "I am so thrilled to be collaborating with Paul again on Grandude’s Green Submarine. I think this is the adventure book we all need during this time, when everyone is stuck at home and longing to travel to exciting new places.  I really enjoyed drawing the newest character in the book, Nandude, particularly because we both share a love of playing the accordion."

We’re delighted that he has a new Grandude adventure to tell.'Hey Grandude!' has been a global sensation and it has been a joy to see children, parents and grandparents around the world taking Grandude to their hearts.
