Turn up the volume and get ready to rock out with the loudest boy in town. Horrid Henry has only one goal in life: to see his absolute favorite band, the Killer Boy Rats, perform live in concert. Unfortunately, his family has other plans and buys tickets to the agonizingly boring Daffy and Her Dancing Daisies show instead. Naturally, Henry will stop at nothing to manipulate his way into the rock concert of his dreams. But his musical ambitions are just the start of the chaos. In this hilarious collection of four stories, Henry and Perfect Peter wage an endless war of bedroom invasions, Moody Margaret hosts a disastrous secret club sleepover, and Miss Battle Axe forces her miserable class to write their own autobiographies. Packed with sneaky tactics, funny feuds, and classic Henry antics, this book strikes the perfect chord for readers who love a good laugh. Grab your backstage pass and join the mayhem.
