Cassy lives with her granny, until the night that she hears strange footsteps coming into their flat. The next morning, she is packed off to her mum's - a squat in London that her beautiful, simple mother shares with a couple of actors. Cassy does her best to throw herself into her mother's life, even agreeing to take part in their travelling show called 'Wolf'. But she can't ever get rid of the feeling that something is following her, and something bad is going to
happen.
Her fear grows as time passes, until Cassy knows she must face up to her past: who her father is, why he left and where he has gone.
What she doesn't know is that some questions are better left unanswered...
