Ages 9–11

The World's Worst Children by David Walliams is best for children aged 9–11. It has no violence, nothing scary, no romance and no bad language. Worth knowing: Gross-out humor (mild).

Ten cautionary tales introduce spectacularly misbehaving children whose selfish, disgusting, or cruel habits lead to comic consequences.
