A young girl called Tozi stands at the bottom of a pyramid, waiting to be led to the top where her heart will be cut out.... Pepillo, a Spanish orphan who serves a sadistic Dominican friar, is aboard the Spanish fleet as it sails towards Mexico....

Five hundred desperate adventurers are about to pit themselves against the most brutal armies of the ancient Americas, armies hundreds of thousands strong.

Less than 50,000 years ago mankind had no art, no religion, no sophisticated symbolism, no innovative thinking. Then, in a dramatic and electrifying change, described by scientists as "the greatest riddle in human history," all the skills and qualities that we value most highly in ourselves appeared already fully formed, as though bestowed on us by hidden powers. In Visionary, Graham Hancock sets out to investigate this mysterious "before-and-after moment" and to discover the truth about the influences that gave birth to modern human mind.

From 1990 to 1995 Dr. Rick Strassman conducted U.S. Government-approved and funded clinical research at the University of New Mexico in which he injected 60 volunteers with DMT, one of the most powerful psychedelics known. His detailed account of those sessions is an extraordinarily riveting inquiry into the nature of the human mind and the therapeutic potential of psychedelics. DMT, a plant-derived chemical found in the psychedelic Amazon brew, ayahuasca, is also manufactured by the human brain. In Strassman's volunteers, it consistently produced near-death and mystical experiences.

In this anthology, edited by best-selling author Graham Hancock, 22 writers illuminate the topic of psychedelics and consciousness like never before. Travel to South America, the American Southwest, outer space, inner space, and back in time to revisit Pahnke's The Good Friday experiment. Explore the effects of ayahuasca, LSD, and much more.
