Harry Potter has finally met his match in the hero of another children's book. Having dominated the bestsellers' charts for nine years, the boy wizard created by J. K. Rowling has been toppled by Alex Rider, a 14-year-old spy from the pen of Anthony Horowitz. Days after the release of a new film adaptation of a novel by Horowitz, Stormbreaker, the author has topped the children’s bestsellers’ charts.
The latest Booktrack figures show that Horowitz now has seven titles in the Top 20 children's bestsellers' list. He said: "I have never felt that I'm in competition with J. K. Rowling. Indeed, I don't think Stormbreaker could ever have been made into a film without the success of Harry Potter. But I can't help smiling quietly to know that Alex has seen off Harry this week."
Much as I love Harry, I can't help smiling also !!
