Ghostwriter behind Millie Bobby Brown's debut novel Nineteen

The Enola Holmes star yesterday thanked ghostwriter Kathleen McGurl on her Instagram, saying she couldn't have written the book without her. The Dorset-based author collaborated with the 19-year-old on her new book Nineteen Steps, which tells the story of an 18-year-old falling in love during London in the Second World War. In a post on her own website, McGurl revealed how she wrote drafts from Millie's ideas. (Pictured from left Millie Bobby Brown, with her ghostwriter Kathleen McGurl)
