Little Miss Sunshine meets About a Boy in this piercingly bittersweet novel which shows how the most meaningful love can last a lifetime.

Willow's mother Rosie isn't like the other mums. She's wears every colour of the rainbow, has midnight feasts, and sends Willow to school covered in paint.

Meanwhile, Rex is the sort of father who checks Willow's homework, has a rule for everything, and would never dream of playing in the dirt.

Now Rosie and Rex live in different places, Willow knows her mum needs her even more. But Rosie's multi-coloured way of looking at the world can be overwhelming. These days, it feels like Rosie is spinning off her axis - and taking Willow with her. As if, one day, Rosie might disappear for good.

And what would happen to Willow then?
