A Radlett author is hoping to write a book to raise thousands of pounds to help a four-year-old boy walk.

Marion Herts, who raised £2,000 for charity with her last book, heard about an appeal for Noah Collins who has cerebral palsy.

His parents, from Watford, need to raise £80,000 for an operation in America to help him walk and have a life "free from pain."

Mrs Herts said: "The first book did so well for charity I decided I wanted to do another, but this time concentrate on just one charity that was in need of support.

"I saw Noah’s story in the paper and thought it would be the perfect cause to raise money for."

Noah was diagnosed with cerebral palsy when he was a baby, and he may need a wheelchair permanently when he is older.

He has been accepted for an operation in America to ease tightness in his muscles.

Mrs Herts added: "I hope to have the book ready for Christmas next year, and hope to help this inspiring local child."
