Secrets hidden in the darkness of the sea...

Stolen at birth by her sea-lord father, Copper is returned to her mother, the queen, to experience life on their island home. But something is missing within her, for she is without a soul. Copper is adrift and alone until strangers come with Companion creatures and tell her of her destiny. For Copper is the Sea Dancer, one of five elements incarnate, and the fate of the world depends on the Dancers joining.

Yet there are those who would pervert the Dancers' destiny, and an Emperor who will stop at nothing to prevent them from finding one another. As conspiracies unfold, and secrets are pierced, the upwelling of power that Copper controls is put to the test.

The uneasy marriage of land and sea is about to break apart. And all hangs on Copper's choice...
