Baktun 2012 by Heather Conrad

It is the year 2011 and the comet Raven is entering our solar system. A Mayan womanÂ-an astronomer and teacher, predicts there is more to Raven than first appears. Her former student, Karen Rune, is living in San Francisco. Karen is troubled by strange dreams and sleep-states since the death of her lover. Recalling her teacherÂ's words about the baktun cycles of the ancient Mayan calendar and the concept of zero, Karen travels with a friend through Mexico in search of her teacher, the apparitions in her dreams and the meaning of Raven.
