'I never sleep, the night before my birthday . . . it's the only day of the year I hear from her . . .'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 it.

Dizzy has kept everything. This year is different. Nothing comes in the post, but something amazing is about to arrive on Dizzy's doorstep.

Something that will whisk her away - and put Dizzy's world in a spin.
