revolutionary technology that allows small groups of minds to unite, forming a single consciousness that experiences the world through multiple bodies. But as two best friends discover, the light of that miracle may be blinding the world to its horrors.Chance and Leap are jolted out of their professional routines by a terrifying stranger—a remorseless killer who freely manipulates the networks that regulate life in the post-Join world.

What does it mean to be human, and what happens when humanity takes the next step in its evolution? If the individual mind becomes obsolete, what have we lost and gained, and what is still worth fighting for?
