Because there are many of us. Taylor D.

Bob's universe is expanding. All new colonies are built to transport people to new worlds.

Immortality gave many opportunities, but also brought many sorrows. Replicants begin to understand how fragile and finite the lives of people and creatures of other worlds, and therefore - how valuable are.

exploring the cosmos, Bob opens another type of intelligent creatures, but they - evil in pure form and directly threaten survival of survival humanity. While Bob has not suffered defeats, but this time everything can end for him differently.
