Breed - A Breed Novel, #1

A comet is set to destroy Earth, but Kyle Singer is determined to survive. Tired of being treated like a second-class citizen thanks to her perfect brother, Kyle doesn't think twice when offered the opportunity to attend an academy formed to stop the comet. It's not like there's going to be much left after the comet hits, anyway. She's drugged, shipped off to the school, and thrown into a relationship with Ichiro Seung-hun, an exchange student from South Korea.
The school isn't just about stopping the comet. It's a breeding program for after the comet hits and wipes out the human race. Terrified of becoming a baby-making factory, Kyle and Ichiro will do whatever it takes to escape. Even if that means dying.
