Indie's mum loves the colour blue. Blue is the colour of her favourite things - bluebirds, bluebells, the sky.

So much so that she named her children Indigo and Misty - shades of blue, special colours, magical colours.

Indie loves her mum. But blue isn't always a happy colour - and there's a lot of sad stuff in her mum's life. And now suddenly she wants them to run away from their lovely house and leave Max - mum's fella - behind.

Indie doesn't know why. Or where they're going. Or how to tell her friends. In a dingy old flat with a grumpy neighbour, no heating and only biscuits to eat, Indie begins to realise that her mum's got a secret - a reason she really needed to get away.

Indie mustn't let her go near Max again - or something terrible will happen.

A powerful, moving and tender book about love, family, domestic violence - and what it feels like to get the blues.
