At the cliff-hanger ending of Sean, Tate loses the scanner, the very thing he was fighting to protect, which his father had called the key to human survival. Tate doesn't have much time to worry about it because he needs to ensure that he and Christina are safe. His father left him one last thing that can do just that - a safe house, which turns out to be a clue to what's really threatening the planet. The Sicarii, a parasitic race, the same parasitic race that invaded the H2 planet four hundred years ago, has designs on Earth. This forces an uneasy alliance between the Fifty and the Core. Together they unite in the fight of their lives against an enemy they are only beginning to understand.
