The Angle Quickest for Flight — Steven Kotler

In The Angle Quickest for Flight, a quintet of eccentric metaphysicians searches for a sacred book looted during the Spanish Inquisition and tithed to the Vatican. Steven Kotler's first novel, which received acclaim from masters such as John Barth, moves with dizzying power across continents and epochs, weaving a multilayered narrative around secret societies, mad magicians, and a runaway boy named Angel.
