With humanity coming up fast on 2012, publishers are helping readers gear up and count down to this mysterious - some even call it apocalyptic - date. Since November, at least three new books on 2012 have arrived in mainstream bookstores. Journalist Lawrence Joseph forecasts widespread catastrophe in Apocalypse 2012: A Scientific Investigation Into Civilization's End. Spiritual healer Andrew Smith predicts a restoration of a true balance between Divine Feminine and Masculine" in The Revolution of 2012. In 2012, Daniel Pinchbeck anticipates a "change in the nature of consciousness." Each arrives in the wake of the 2006 success of 2012: The Return of Quetzalcoatl, which has been selling thousands of copies a month since its release in May. The books also build on popular interest in the Maya. Authors disagree about what humankind should expect on Dec. 21, 2012, when the Maya's "Long Count" calendar marks the end of a 5,126-year era. Maya civilization, known for advanced writing, mathematics and astronomy, flourished for centuries in Mesoamerica, especially between A.D. 300 and 900. Its Long Count calendar ... tracks more than 5,000 years, then resets at year zero. Publishers seem to be courting readers who believe humanity is creating its own ecological disasters and desperately needs ancient indigenous wisdom. Part of the 2012 mystique stems from the stars. On the winter solstice in 2012, the sun will be aligned with the center of the Milky Way for the first time in about 26,000 years. This means that "whatever energy typically streams to Earth from the center of the Milky Way will indeed be disrupted on 12/21/12 at 11:11 p.m. Universal Time," Joseph writes.
