Sally and her team are only now beginning to see what the alternate version of history has in store for them and how the Szzzyyyxx unscheduled visit to Earth changed things.  But then they begin to wonder how cooperative their friends were with the growing tyranny.

Sally, Ian, and Diego get a first look at what has become of their history and get insights both into what happened and what the results meant to people they became.

Sally awakens to find that Diego had not exaggerated about what he had seen.  They find themselves inside a control room managed by their own imaginations, but capable of almost anything, including a round trip to Leningrad in 1964.  But the Szzzyyyxx had gotten there first, and they had done some damage.

Diego's strange illness grants him amazing insight to the nature of the planet and its purpose.  Sally and Ian choose to risk joining him, but something neither of them could imagine is brewing under the surface.

While trying to care for Spotty, who has mysteriously vanished, Diego develops an unusual illness.  In the midst of this, Jackie makes a critical discovery about the nature of the world they are on.

Following the path left by the missing Szzzyyyxx ships leads Sally's crew to an unexpected trap.  Like the other ships, they turn into the event horizon, but within there find themselves in an unknown and mysterious world that seems too perfect.
