Which novel won J.K. Rowling the 1997 Smarties Book Prize in the 9–11 years category?

Harry Potter and the Philosopher’s Stone won the 1997 Smarties Book Prize in the 9–11 years category.

The award was one of the early signs that Rowling’s debut had connected strongly with children and booksellers. The Nestlé Smarties Book Prize was a major British children’s literature award, with winners selected through a combination of judging and children’s involvement.

The novel also won the overall Smarties Book Prize in 1997, helping establish it as more than a niche fantasy publication. It had been published in Britain by Bloomsbury on 26 June 1997 and quickly attracted enthusiastic reviews.

The book’s title differs across English-speaking markets. Britain and other countries use Philosopher’s Stone, while the United States edition uses Sorcerer’s Stone. Both refer to the same first Harry Potter novel and the same 1997 award-winning story.
