Zecharia Sitchen's The 12th Planet is the starting point on a quest that spans six books and 20 years worth of ancient aliens, genetic manipulation, and scrutiny of linguistic minutiae. If we trust Sitchen's translation abilities, we must be prepared for the imminent return of an alien race who created us some 300,0x00 years ago. The 12th Planet is perhaps the best written of Sitchin's Earth Chronicles series; full of example after example of ancient Sumerian passages, astronomical observations, archaeological finds, and technological coincidences supporting his theories. The price we pay for all this evidence is a bit of a dry read at times, but the ideas Sitchin proposes are more than scintillating enough to make up for the overtly scholastic tone of his text. --Brian Patterson
