Starbound

After spending six years travelling to a distant solar system that is home to the enigmatic, powerful race known as "The Others," in the hopes of finding enough common purpose between their species to forge a delicate truce, Carmen Dula and her husband return to Earth to find a massive flotilla of warships defending Earth against The Others. But The Others have more power than anyone could imagine--and they will brook no insolence from the upstart human race.
