Here’s an extract:
This story is a marriage of text and illustration, each interdependent as they should be in quality picture books. At first the little girl sees only the rainbow, even though there are other spots of colour around her, as she thinks nostalgically of the colours of the country but as she starts to see more of her environment, so too the colours in the pictures increase although the city remains grey and the country bathed in light. And as her thoughts slowly attune to the city environment she begins to see more objects, different from the farm but perhaps with something to offer as she peers over the blue fence and sees a treehouse with a rope ladder and maybe a friend.
