When the dead start singing, the living must listen.
Disgraced Egyptologist Aris Thorne hears something impossible-ancient pyramids humming with a frequency that shouldn't exist.

Racing a shadowy corporation through hidden chambers and impossible architecture, they activate something that was never meant to sleep forever. Deep beneath Antarctica, the network's heart awakens-and sends humanity's location screaming across the galaxy.
They thought they were archaeologists. They were actually pressing the doorbell.
