Gillian Sands vows vengeance for the dead refugees after the latest terrorist attack on Thunder City. From the depths of Mystic Bay, she assists the other alternative 'Alt' humans by finding the bodies. Someone has to pay, but only Evan Blackwood is willing to help.

Evan Blackwood jumps at the opportunity to work with Gillian, not because her gills intrigue him, but because of her fierce devotion to her mission. If only the vicious flashback of falling from the sky and into a raging inferno would stop.

As their investigation deepens, Gillian begins to see underneath Evan's façade, but when morals are tested and desire burns bright, can Evan stop Gillian from breaking the law? Or will he lose her forever to the murky waters of Mystic Bay?
