What was favourite author in once by Morris Gleitzman?

In the book "Once" by Morris Gleitzman, the main character, Felix, doesn't explicitly state a favorite author. However, he is a huge fan of books, especially stories about dragons.

While we don't know Felix's favorite author, the story does hint at his love for fantasy and adventurous tales. He even starts writing his own story about a dragon.

Therefore, it's safe to assume Felix would enjoy authors who write in the fantasy genre, perhaps someone like J.R.R. Tolkien or even a more modern author like Rick Riordan.
