Seven-year-old Charlie thinks he is invincible. He is convinced he has a clock for a heart, which makes it impossible for him to die or feel the sort of heartache his mother always feels every time she and Charlie must flee another abusive loser who doesn't deserve a woman like Charlie's mum.
But yet again Charlie and his mum find themselves at Aunty June's in Brighton on the south coast of England. And while Charlie's mum seeks refuge, Charlie himself lets his curiosity get the better of him in his latest attempt to prove his own immortality.
That's when he meets him. The boy who saves Charlie's life. The boy from Brighton.
