Something is killing off immortals, one by one.
Taelen Jessit is an alien emissary on a mission sanctioned by the U.S. government to search for ancient gods. His hunt leads him to a dig headed by archaeologist Rachel Cruz. When his military entourage forces Rachel's team out of the cave they were exploring, a flash flood hits the riverbed and threatens to tear them through the ravine.
In the aftermath of the flood, Taelen witnesses the incredible healing of Rachel's broken ankle and believes his gods have blessed her. He is inexplicably drawn to her, and she to him.
What Taelen doesn't know is that Rachel is Nephilimâ€”a descendant of the gods his people worshipâ€”masquerading as a human to find the god-killer and destroy it. Rachel needs help to bring down the tech that is manipulating the Earth's magnetosphere and frying her people alive. She's given Taelen her heart, but can she trust him with her secret?
