Orphaned by Rome’s savage legions, Thea, a slave girl from Judaea, has learned what it takes to survive. She knows only violence until a chance meeting with gladiator Arius offers a shred of tenderness. But their bond is severed when Thea is sold again, condemned to rot in squalor. Years later, a singer known as Athena betrays no hint of her troubled past. Catching the eye of the Emperor himself, she is swept into a world of decadence and depravity. But although Domitian fears betrayal from every side, he is unaware that the greatest threat lies next to him – a slave girl who has come to be called the Mistress of Rome...
