The Andalusian Covenant

The year is 1492, and two worlds are about to collide - but not the way history remembers. As the last Muslim stronghold of Granada crumbles under Catholic siege, an extraordinary conspiracy takes shape in the city's final days. Ibrahim al-Zarqali, a renowned physician whose healing arts transcend religious boundaries. Samuel Cohen, a rabbi whose intelligence networks and navigational knowledge make the crossing conceivable.
Zahra al-Rundi, a survivor of Ronda's brutal conquest, carrying secrets that could save - or damn - them all. And Ismail al-Qurtubi, a naval commander whose brother died defending the impossible, now tasked with navigating the truly impossible. Their plan defies every law of politics, religion, and common sense: steal Columbus's navigational secrets and sail west, carrying the accumulated wisdom of eight centuries of coexistence in Al-Andalus to whatever lies beyond the vast Atlantic.
But their expedition carries more than refugees - it bears a revolutionary idea. The Andalusian Covenant, a document that dares to imagine a society where Islamic mathematics converses with Aztec astronomy, where Jewish physicians learn from Taíno healers, where leadership depends on knowledge rather than bloodline or creed. Guided by Miriam, Samuel's brilliant daughter who disguises her gender to practice astronomy in a man's world, they discover not just new lands but new possibilities for human civilization.
From the courts of Tenochtitlan to the highlands of the Inca, from Caribbean islands to the return journey to a changed Europe, they must prove that cooperation can triumph over conquest, that knowledge shared multiplies rather than diminishes. The Andalusian Covenant is alternate history at its most ambitious: a sweeping epic that spans continents and centuries, challenging everything we think we know about 1492 and offering a vision of the Americas that never was, but perhaps should have been.
