A South American engineer lands in the Sultanate of Oman with a precise assignment: to open a road through the Al-Hajar mountains. He brings formulas, heavy machinery and the certainty that rock is only a problem of calculation. But the mountain has a memory. The warnings come sideways: a banker who lowers his voice, a foreman who refuses to climb a certain slope, a silhouette in the rearview mirror. And, at the bottom of a cave, an ancient Guardian who does not collect in money.

Jinn: The Guardian of the Mountain is a memoir-novel in which engineering and the ancestral folklore of Arabia meet in the same gorge: the story of an impossible project, of a people who teach a stranger to see differently, and of the price the land demands from anyone who dares to enter its depths.
