Frances is in a new house in a new neighbourhood and going to a new school, but no amount of new can make her forget the old, sad secret dragging at her heart. Not the pictures of bacteria that she draws with painstaking precision, not even Picasso, the puppy with the long soft ears and the cute black circle like a target on his bottom.

Then Frances meets Kit, the tall, quiet boy with the two-coloured eyes. Kit is a real artist. His coloured pencils fill page after page of exercise books. He sees wonder in the rocks and ferns and sky. Though Kit has worries of his own.

But when secrets are spilled, Frances's life turns grey and drab. Not even Picasso's wet nose can brighten her up. Frances and Kit will need to face the truth of their pasts to find colour in their world again. After all, don't the most brilliant sunsets need a cloudy sky?
