A ragdoll, a postcard from Marrakech, a rainbow-stripe hat, a dreamcatcher, a silver necklace with a pink stone in. Dizzy's mum left when she was small. But every year, on her birthday, something arrives in the post – a present or a card with her mum's loopy writing on. Dizzy has kept everything. But this year is different. This year's present is her mum, in person. Tanned and skinny with loads of earrings and a huge smile, Storm is a human whirlwind. She whisks Dizzy away for a summer that puts her whole world in a spin.
