Horrid Henry encounters the worst babysitter in the world; traumatizes his parents on a long car trip; goes trick-or-treating at Halloween (with disastrous results); and emerges victorious from a raid on Moody Margaret's Secret Club. Francesca Simon is one of the world's best-loved children's authors. She is the only American to have ever won the Galaxy Book Award, and her creation, Horrid Henry, is the #1 bestselling chapter book series in the UK—with a hit TV show and over fifteen million copies sold! Each book contains four easy-to-read stories and hilarious illustrations by the one and only Tony Ross, so even the most reluctant of readers won't be able to resist Henry's amazing talent for trouble! A global publishing phenomenon with 12 million copies sold!
