How far would you go to save the human species?

Heart to blood, muscle to bone, tourist flesh above my own. It’s the bridgers’ directive: risk your own life to save tourists bridging to alternate worlds. Bridger Infinity Fowler has no qualms about the directive. Risking death is just what bridgers do. But now the earth is dying. Bridgers have a new directive-save as many humans as possible, even if some must be sacrificed in the process. Sacrificing lives is not what Infinity signed up for.

Desmond Weaver, determined to help save the human species, has volunteered to be Infinity’s partner. He has ingenuity and grit, but is this enough to make it as a bridger?

Their mission: bridge 718 refugees to a new world and establish a colony. If the world is occupied, avoid conflict and learn to coexist.

Once bridging begins, there is no turning back. The new world is indeed occupied, but not by humans, and avoiding conflict isn’t so easy. As violence erupts, Infinity and Desmond realize they may have only one hope of saving the colony-sacrificing refugees they have sworn to protect.
