At eight years old, Lucia is torn from the life she knew. Her village burned to the ground and parents murdered by Romans, she is kidnapped, sold and shipped abroad to the Villa Tempestatis in Britannia to serve the young Roman army officer Castus.

Faced with a bleak future of decades of servitude to her master, as well as sadistic brutality at the hands of his slave and manageress, Paltucca, she finds herself fixated by one thought alone. Fuelled by hatred and a belief that the gods saved her for a reason, she vows to never taste freedom until she gets her revenge.  

As she and her fellow slaves are exploited mercilessly by the master and his 'noble' friends - and brutally punished for even the smallest misdemeanours - Lucia’s longing for vengeance only grows stronger. Despite warnings from her loyal friend, Sennianus, that her hatred won’t bring her happiness, she continues to plot the downfall of Castus and Paltucca.  

When Paltucca performs an unforgivable act, cruelly destroying a chance of happiness for Lucia, the manageress seals her own fate and unwittingly becomes her own undoing. But what will become of Castus? Risen within the ranks and trusted by the master, Lucia must decide whether or not to exploit her power and risk everything to fulfil her lifelong desire.
