Underworld

The Shadows have invaded Earth, but no one's listening. Jas Harrington's returned to Earth after defeating the Shadows and escaping their clutches, only to find the hostile aliens have already invaded her home planet. Everywhere she turns, Shadows are walking among Earth's population unnoticed. They've infiltrated the government, and they're building their Shadow traps, ready to launch a full-scale assault. Jas has to find a way to stop their spread, but she stumbles into Earth's underworld subculture. Society's rejects, the underworlders refuse to help. In fact, they cross her at every turn. Can Jas prove that Earth is under threat and make the government fight back? Can she overcome the obstacles the underworlders put in her way? If she doesn't succeed, the Shadows will overrun Earth and destroy humankind forever.
