Katie's birthday is on its way. Last year her mum gave her a book on Botany! This time she wants some rollerblades and a computer. But her mum thinks that rollerblades are dangerous and computers cost a lot of money. She goes for a walk in the botanical gardens with her best friend, Isis. They are surprised to see Katie's cat, Solomon, is there too. So Katie turns Isis and herself into cats, and they follow Solomon through the undergrowth. What do they discover? Katie the Witch returns to Storynory!
