Jenna Tyler has never seen the sun. She has never been outside. She has never breathed real air. No one on The Ark has. After a nuclear blast unleashed radiation onto the world, Earth has been un-habitable. Until now. One hundred prisoners are sent down to Earth, because The Ark is running out of oxygen. The Ark is a space ship that saved the last of mankind, or so they believed. A lot is in store for Jenna, especially when she falls for a certain King.
