This is the story of a most unusual relationship; Fala the Slider Girl and Bartek her Watcher. No mere chance has brought them together, it is their destiny. Although neither knows it, theirs is a love as deep as the oceans and as enduring as Gaia, our earth which birthed and protects them. But the time is coming when Gaia will be threatened by a far greater power. To resist, Gaia will need their courage, and she will demand they both sacrifice their all, including each other.
