Thetis

Blind and broken, orphaned teenager Jonah Lincoln reluctantly boards a rescue ship bound for the planet Thetis, but not before it picks up a few more surprising and dangerous survivors from the massacre on the moon Achilles. After regaining his sight, Jonah sees the gated colony on Thetis is just as he feared--cloaked in mystery and under an oppressive rule with no one to trust--and that outside the walls, it's even worse.
