Anne Le Clair travels to Glastonbury with her fiancé, Egyptologist and mystic Michael Levy, to investigate a house she inherited from a mysterious aunt only to find trouble waiting. One of Avalon's sacred twin springs is failing. Together, Anne and Michael try to restore the water flow, but discover there is much more at stake: the Illuminati master Alexander Cagliostro has activated an ancient crystal tower, tearing a hole in time which threatens much more than one sacred spring. Meanwhile, in ancient Atlantis, Megan, priestess of the Crystal Matrix Chamber, flees the destruction of her world carrying with herself a vital artifact.
