Audible is a website that lets you listen to a book and just lose yourself in the story!
You can use Audible on any device and although headphones would be helpful, you don't need them.

The books are organised in age ranges which should help you choose. In the 'Tween' section, maybe Year 4 and 5' there is a book called 'White Fang' - one of my favourites! If you read it, please let me know what you think!
