13-year-old Richard ‘Trick’ Hope is used to getting into trouble, but not like this. After an argument with his dad about him hanging out with the wrong crowd, Trick is furious. He sees his friends that night, but they get into trouble with the police and are chased across London. Trick hides in the vaults of the British Museum, where the pendant he always wears – the only memory he has of his mother – starts to pull him in further. A blinding flash of blue light and then … He wakes up face down in sand. Sand? He’s on a beach. A figure in armour is racing towards him, ready to attack. He’s not in London anymore.
