Eighteen years have passed since the Core Civilization was defeated; New Britannia and the Colonies are flourishing and their populations growing. Grady decides that it's time to go home to Britannia. The planet has recovered from the damage done by the Core Alien's attack and is ready to be resettled. The Henricks children will be graduating in a few months and there's nothing standing in the way of them going back home to the planet they were born and raised on. Thousands of the Britannia survivors will join them in the Home Coming. However, at the end of the war with the Core Civilization, Taffy neglected to share some information she was given by the scouts investigating the Stealth Civilization. It was a small omission but when it comes out, the plans for a Britannia home coming are thrown for a loop. Grady calls off the move to Britannia but sometimes going back home isn't an option. Things can have a way of forcing you to do what you planned anyway.
