When Archaeologist and University of Toronto Professor Molly McBride is given a strange collection of artifacts by a museum patron, she feels compelled to investigate. She discovers that one of the artifacts is the key to another world, a doppelganger Earth called Gaia. Life on Gaia seems idyllic at first, but Molly soon learns the society harbours a dark secret. Renegades on Gaia have build a stronghold on Earth in which they are able to carry out experiments with terraforming and phase shifting. But the more the renegades shift, the more damage they do to both planets, and the more the gap between the planets narrows. Can Molly and her Gaian allies prevent the impending cataclysm?
Molly finds a key. Travels to another world. Tries to save both worlds.
