Lucy Wright, sixteen and a paraplegic after a recent car accident that took her mother's life, lives in Queensland on a 10,000 acre farm with her father. When Lucy investigates strange lights over the creek at the bottom of the property, she discovers a mystery that links the lights to the science of cymatics and Scotland’s ancient Rosslyn Chapel.

But beyond Chapel is an even larger mystery. One that links the music the Chapel contains to Norway’s mysterious Hessdalen lights, and beyond that to Saturn and to the stars. Lucy’s discoveries catapult her into a parallel universe connected to our own by means of resonance and sound, where a newly emerging world trembles on the edge of disaster. As realities divide, her mission in this new world is revealed and she finds herself part of a love story that will span the galaxy.
