Why did Jack the Ripper commit the appalling acts of butchery in Victorian London then apparently disappear without trace?Why did the Titanic sink in 1912 despite perfect sailing weather and numerous warnings about the presence of icebergs?What compelled Adolf Hitler to sanction the deaths of over six million innocent people in the 1930s?The answers lie in Revelations 2012Seth (God of Chaos) was cast into the underworld after killing his brother Osiris; a mighty king worshipped by the Ancient Egyptians. The only link between Seth and the earth is a ceremonial obelisk and four 'keystones'. Each keystone is in fact a device through which Seth is able to manifest his evil and generate a fresh 'life-force' strong enough to allow him to return to earth. It has taken thousands of years' of sacrifices, performed by generations of civilisations, for the life- force to reach the proportions that will enable Seth to return and wreak havoc.In 2012, 'Precession' (a natural cycle whereby the stars and planets appear to change position in the sky) will realign thousands of sacrificial temples across the globe with the celestial template on which they were originally constructed and the Portal through which Seth was originally banished will be re-opened. Only one person lies in the way of Seth and the Apocalypse; Kate Stone, an anthropologist who has discovered that Nostradamus and the Mayans were correct with their predictions about 2012 and the end of the world. But can she intervene in time?
