Bea and her mum are moving in with her grandparents, which will mean a new school, new friends, and big changes for Bea. All Bea can remember about Granny and Grandad's house is their big, beautiful garden with its colourful flowers and secret hide-and-seek spots, but when Bea and her mum arrive, the garden has grown sad and neglected. The wild garden feels like the perfect place for Bea to hide away from all the changes in her life, but when she hears a strange noise in the long grass, she can't quite believe what she finds. Four tiny dogs, no bigger than mice! Follow the adventures of Bea and the tiny dogs as they become friends and work together to save the garden!
