On a fateful train trip from Manchester to London in 1990, a young single mother named Joanne Rowling conceived the idea of a children's book about a boy wizard named Harry Potter. Five years later, that idea became the basis for the most successful book franchise in the history of publishing. Poppy Montgomery (Without a Trace) stars as the author who struggles to bring the beloved wizard fantasy of Harry Potter to life while living as a single mother on welfare, and later becomes one of the world's wealthiest women and most prolific writers. Based on a bestselling biography, "The J.K. Rowling Story," this Lifetime Original Movie co-stars Emily Holmes and Antonio Cupo.
