The Doomsday, But I Have an Invincible Shelter

When the Evernight plunges North America into darkness, monsters that feed on people begin hunting through the night. The story follows a survivor who reawakens into this ruined world with a secret advantage: a shelter no danger can breach. Hidden protection is rare in a land where humans are struggling just to endure, and every night tests how long that safety can last. The tension between staying hidden and reaching out to others drives the romance at the heart of the tale.
