This age group is – nominally – nine to twelve, but in practice, bright younger children can enjoy Middle Grade books, as can adults.
Many excellent MG books aren’t available as audiobooks, alas. So, you’ll have to invent your own funny voices and flying machine noise in Howard Whitehouse’s hilarious “Mad Misadventures” series, set in Victorian England:
Our recommendation for an audiobook is Neil Gaiman’s wonderfully creepy, yet touching Graveyard Book, about a living boy raised by the ghostly residents of a cemetery. There’s a lot to this story about bravery and loyalty – it’s not just a horror tale!
