Annihilation has a way of following some people. Infinity and Desmond are bridgers, sworn to protect travelers to alternate versions of Earth. But now their own Earth has been destroyed, and they have a new task-protecting a small community of fellow refugees who managed to escape to a world teeming with giant arthropods. Stranded there, they've gradually managed to etch out a fulfilling existence. But it seems nothing good can ever last. Infinity and Desmond's hopes of living out their lives in peace are shattered when their old friend Armando inexplicably bridges to their world. Armando's arrival triggers a devastating series of events and forces the bridgers and their fellow refugees to leave their new home. After narrowly escaping, they find themselves entangled in a cruel game, a trial to decide humankind's worth. The rules of the game are unclear, but the stakes are high-the annihilation of billions of people. Caught up in an impossible dilemma, on a world populated by extraordinary sentient creatures, Infinity and Desmond discover the limits of what they are willing to do for their species-and for each other.
