Amber Drake is the only person who can save three worlds from annihilation. Only she doesn't know it yet.

When the Garden fell at the beginning of time, the First One divided what was left into three:

* Humans - administered by the descendents of the Adam and Eve
* The Fae - watched over and protected by those who came from the Angel of the Garden
* Trolls - ruled by those who evolved from the Snake who tempted

Each world was given a sword to protect those who would come and hope for the future in the form of a prophecy that foretold the coming of one born of all three bloodlines who could restore the Garden and bring peace to all worlds.

But the tribred's birth also initiates a series of events that start the Arpeggio Clock to begin the countdown to Armageddon and not everyone wants the clock to stop.
