The sun has been silent for sixty years, and humanity is huddled underground, struggling to survive.
During an unauthorized investigation, Shen Xinghe discovers his father's encrypted files. They contain just one line: "The Stargate isn't an exit. It's an entrance. Don't let them find it."
Twenty-four hours later, a citywide manhunt is launched.
With no other choice, he steps through the Stargate that should not exist. What awaits him on the other side isn't hell, but a truth colder than hell: Earth's apocalypse wasn't a natural disaster. The sun's silence was a "disconnection." Someone doesn't want Earth connecting to the Milky Way.
