There are three things you need to know about Jasper.

1. He sees the world completely differently.

2. He can't recognise faces - not even his own.

3. He is the only witness to the murder of his neighbour, Bee Larkham.

But it's hard to catch a murderer when you can't recognise their face...

An extraordinary and compelling debut which will make you see the world in a way you've never seen it before.
