Galactic Embassy: Earth Division (2014)

Earth has been taken over by the Talir, a hostile species on a colonization rampage throughout the galaxy. It's up to a team of young Galactic Embassy members--both human and not--to take it back. They are led by Mikaila Donner, a former prisoner of the Talir. But as this group of ambassadors will soon find out, there's more to this mission then just following orders.
