In the 22nd century visionary scientist Vannevar Morgan conceives the most grandiose engineering project of all time, and one which will revolutionize the future of humankind of space: a Space Elevator, 36,000 kilometres high, anchored to an equatorial island in the Indian Ocean.

But first he must solve a million technical, political, and economic problems while allaying the wrath of God. For the only possible site on the planet for Morgan's Orbital Tower is the monastery atop the Sacred Mountain of Sri Kanda. And for two thousand years, the monks have protected Sri Kanda from all mortal quests for glory. Kings and princes who have sought to conquer the Sacred Mountain have all died. Now Vannemar Morgan may be next.
