A historically grounded novel of slavery, power, and survival in the ruthless world of the seventeenth-century Caribbean.

1685. When the Dutch merchant Balthasar Coymans secures the coveted Spanish Asiento contract-the exclusive right to supply enslaved Africans to Spain's American colonies-he gains access to the richest slave market in the Atlantic world. Control of this trade promises immense wealth, but it also unleashes fierce competition among merchants, colonial officials, and rival trading networks determined to claim their share.

Across the Caribbean and the ports of Spanish America, fortunes rise and fall with every shipment of human cargo. Contracts are fragile, loyalties shift constantly, and corruption thrives in the shadow of colonial power. Traders, sailors, agents, and intermediaries become entangled in a vast web of commerce, intrigue, and betrayal.

But another power stands in the way. In the Spanish colonies, the Holy Office of the Inquisition watches closely over foreign merchants and their dealings. Suspicion, denunciation, and religious scrutiny can destroy fortunes as quickly as political rivals. In a world where profit depends on fragile privilege, one accusation may be enough to bring the entire enterprise crashing down.

Asiento offers an unflinching portrayal of the economic machinery that sustained the seventeenth-century slave trade to Spanish America. Through vividly drawn characters and meticulously researched historical settings, the novel reveals the ambitions, rivalries, and moral compromises that shaped the Caribbean world.

This is not a tale of swashbuckling adventure. It is a dark and immersive exploration of a system where human lives became commodities-and where power belonged to those who controlled the trade.

Asiento is the third of four standalone historical novels (Sons of Japheth Series) about the Dutch and the slave trade in the 17th century. The novel is included in the literature list of the official Historical Canon of the Netherlands (2025), in the section 'VOC and WIC.'
