From Amazon:

The Immari are good at keeping secrets. For 2,000 years, they’ve hidden the truth about human evolution. They’ve also searched for an ancient enemy–a threat that could wipe out the human race. Now the search is over.

Off the coast of Antarctica, a research vessel discovers a mysterious structure buried deep in an iceberg. It has been there for thousands of years, and something is guarding it. As the Immari rush to execute their plan, a brilliant geneticist makes a discovery that could change everything.
