Shadows of the Earth

The Delta is assembled, but the threat is far from over. Rory travels to the Moon, encountering her grandfather's footprints from fifty years ago. She returns to her parent's home, eager to forget about the last few weeks, but the Shadow persists.

Silas and Cody are covertly led to the Planetae laboratory, but quickly realize there's more to the tokens than their initial assumptions. Waylen struggles to maintain peace as the walls between organizations crumbles. When one of his closest allies betrays them, Waylen's trust is shattered.

Who invented the Delta? What are the Echoes trying to show them? Can they prevent an invasion, or has it already begun?

Shadows of the Earth continues the Token series by Nathan Hystad.
