When merchant clerk Elias Harrow boards a routine voyage along the Cornish coast, he expects trade, not capture. But when corsairs intercept his ship, he is pulled into a vast, unseen network—one where human lives are meticulously recorded, priced, and traded through ledgers rather than chains. In the brutal yet eerily ordered slave markets of the Mediterranean, Elias discovers a chilling truth: this is not chaos—it is commerce. Alongside Marta , a brilliant cartographer who sees patterns where others see survival, and Father Benoît , a priest whose loyalties run deeper than faith, Elias begins to uncover the hidden architecture behind the trade: A system where names become numbers Where ransom is engineered, not negotiated Where power lies not in force—but in paperwork As they descend deeper into the machinery of this shadow economy—through ledger houses, covert water gates, and international intermediaries—they uncover a conspiracy that stretches far beyond the markets themselves. At its peak stands a powerful force: House Virelli —the unseen authority that doesn't capture people… but insures their fate. Now, with a diplomatic hostage at the centre of a multi-layered power struggle, Elias and his allies must do the unthinkable: Break the system from within. But in a world ruled by ink and calculation… Even rebellion must be accounted for.
