Almost halfway to our closest neighbor, Alpha Centauri, a planet-killer, in reality a system killer, arrived to invade the Oort cloud. Unlike all the other inhabitants of the cloud, all moving in response to known system gravitational influences, this one played by its own rules. It’s been over 70 years since our last visit with Buzz and Atticus. Now they and the team face a devastating situation and their only option to help save our entire system is to reach out to a friend in the past.
