Katie is 10 and, one day, on a school trip, she found a stone in her lunch box. But this is not just any old stone we're talking about. It's bright green. It glows. And it writes messages to her. This glow-stone, as she has named it, has changed Katie's life forever. With it's help and guidance, Katie has helped lots of animals, big and small, scary and cute, to get themselves out of trouble. Animals may be stuck up a tree. They may be bullied. They may be too cold. Some may just be lost or have run out of money (yes, animals do use money!). In Katie's first adventure, a giraffe is desperate for Katie's help. The giraffe is terrified of heights and is being dreadfully teased by his cruel brothers and sisters. Katie is magically transported by her glow-stone to Africa, where she teaches the bullies a lesson they won't forget!
