A ship washes ashore in the Philippines without a single crew member aboard. All residents of an alpine village disappear without a trace. Connecting the two events is the appearance of strange, metallic spheres and scorch marks in both locations.

An NSA team led by agents Alton and Mallory Blackwell discover a link between the disappearances and a group of disputed islands in the Artic...and an even more puzzling connection to the ancient city of Sodom. As tensions to lay claim to the coveted islands push the world’s superpowers toward armed confrontation, the Blackwells and their team race to uncover the truth behind the inexplicable vanishings, a truth that threatens to bring a catastrophic end to the modern world.
