The one I am currently into is called '2012, The return of Quetzlcoatl' and its about the end of the Mayan calendar and the spiritual revolution that alot of the world is going through.
Its a very interesting book. Here is a quote from the amazon listing:
Book Description
"Cross James Merrill, H. P. Lovecraft, and Carlos Castaneda -each imbued with a twenty-first-century aptitude for quantum theory and existential psychology-and you get the voice of Daniel Pinchbeck. And yet, nothing quite prepares us for the lucidity, rationale, and informed audacity of this seeker, skeptic, and cartographer of hidden realms.
Throughout the 1990s, Pinchbeck had been a member of New York's literary select. He wrote for publications such as The New York Times Magazine, Esquire, and Harper's Bazaar. His first book, Breaking Open the Head, was heralded as the most significant on psychedelic experimentation since the work of Terence McKenna.
But slowly something happened: Rather than writing from a journalistic remove, Pinchbeck-his literary powers at their peak-began to participate in the shamanic and metaphysical belief systems he was encountering. As his psyche and body opened to new experience, disparate threads and occurrences made sense like never before: Humanity, every sign pointed, is precariously balanced between greater self-potential and environmental disaster. The Mayan calendar's "end date" of 2012 seems to define our present age: It heralds the end of one way of existence and the return of another, in which the serpent god Quetzalcoatl reigns anew, bringing with him an unimaginably ancient-yet, to us, wholly new-way of living.
A result not just of study but also of participation, 2012 tells the tale of a single man in whose trials we ultimately recognize our own hopes and anxieties about modern life."
He has been to some amazing places. I am currently reading a chapter where he went to Galstonbury to visit recent crop circles and listen to a conference on the same. It was very interesting to hear people takes on how 'real' crop circles have evolved over time and their correlation to our spiritual advancement. Its almost as if who (or what) is making these have been slowly introducing more complex patterns as we can better understand them. Very interesting shit. I highly reccomend it.
