Burglar Trouble! Oli and Skipjack have a plan: to punish mean old Mr Grimble by kidnapping all his garden gnomes. The World's Best Jewel Thief also has a plan: to become very rich by stealing the Black Star diamond from the town museum. When these two plans collide, it's trouble! Full of twisty plots, wacky characters and calamitous comedy, "Gnomes are Forever" is the perfect read for fans of Jeremy Strong and Horrid Henry.
