AD 51. Bran is a slave, a prisoner of Rome, but dreams of one day returning to his homeland, Britannia, to fight against the Romans. When the proud young slave is overheard criticizing Rome, he is thrown into prison and faces execution the next day. Luckily, his cell mate Caratacus is a very special prisoner indeed - a British chief. He believes he has a way to save both their skins, but he"ll need Bran"s help. A tale based on a key moment in Roman history, full of Terry Deary"s dark humour and dry wit.
