Sienna Olsen likes to read. The 9-year-old says she can read roughly 100 books a week but now she will have a book that will forever be her favourite.

Sienna's illustration will be on bookshelves across the world this week in JK Rowling's new book, The Ickabog - and she already has a copy with Rowling's signature.

She is one of four children in New Zealand and one of 34 across the globe to have her illustration printed.

"My mum came into the room and told me I had won, and I literally did a jig of happiness," Sienna said.The Ickabog was released, chapter by chapter, earlier this year while the world bunkered into lockdown.

Rowling, who is best known as the author of the Harry Potter franchise, then invited children from around the world to illustrate the book chapter by chapter.'
