Human transcendence
The first implication of the plot is that humans are only partial in their current existence. The research that puts Dr. Kate Warner's life in jeopardy is that she is coming close to being able to activate the "Atlantis Gene," which allegedly turns a human into a supernatural, alien-like entity, like the Atlanteans who live under Antarctica (in the novel).
This is a symbolic representation for an idea called Transcendentalism, or the belief that humans should go through a second transformation (children transform into adults, and then adults transform into super-humans). There are hints in the novel that this transcendent ability in the human genome comes from latent alien data in our DNA that, when activated, returns our alien powers.
Genocide, evil, and terror
The novel deals with eugenics, the manipulation of the human genome through science. The Immari are committed to sole ownership of this genetic "magic" so they can use it for their political and ideological purposes. We learn that this secret society has been involved in many of the earth's most heinous moments, like the Holocaust and 9/11. Kate and David represent a resistance to the dominating powers of the Immari. They are "good guys" fighting "bad guys."
Secret society
Secret societies are conspiracy theory gold, and this novel is no exception. The Immari group reminds the reader of the Illuminati or the Freemasons. This Immari society is allegedly more than 2,000 years old, and they possess esoteric knowledge about superhuman races that live on earth and abroad, and they allegedly possess knowledge about alien life and the origination of human consciousness.
