Lost meets The 100 in this action-packed YA science fiction series-starter. WE'RE ON OUR OWN NOW... The year is 2221, and humans have colonized a planet called Thetis in the Silver Foot Galaxy. After a tragic accident kills dozens of teenage colonists, Thetis's leaders are desperate to repopulate. So Earth sends the Mayflower 2 --a state-of-the-art spaceship--across the universe to bring 177 new homesteaders to the colony. For Jonah Lincoln, an orphaned teen who has bounced between foster homes and spent time on the streets of Cleveland, the move to Thetis is a chance to reinvent himself, to be strong and independent and brave, the way he could never be on Earth. But his dreams go up in smoke when their ship crash-lands, killing half the passengers and leaving the rest stranded--not on Thetis, but on its cruel and unpopulated moon, Achilles. Between its bloodthirsty alien life forms and its distance from their intended location, Achilles is a harrowing landing place. When all of the adult survivors suddenly disappear, leaving the teenage passengers to fend for themselves, Jonah doubts they'll survive at all, much less reach Thetis--especially when it appears Achilles isn't as uninhabited as they were led to believe.
