When Cassina is blown-up by a bomb in a station in England, life as she knows it is over. Except that she doesn't die. Cassina survives as something that can live in the heads of humans, knowing their thoughts but powerless to change them. She ends up in a variety of minds - her mum's, her dad's, a mad old lady's, a bigot's - but most scarily of all, she ends up in the head of the man who murdered her. It's an experience that challenges her beliefs and preconceptions, that terrifies her and frustrates her but, most of all, that changes her. Can it change her killer too...? This is Cassina's story, in her voice - a voice that will grip you and goad you, make you laugh and make you cry. It is a voice you will never forget.
