Invisible (Invisible #1‪)‬

The country has never been less united. Segment living has been the way of life for longer than anyone can remember.

Zya is ready for her Exit Exam, knowing that she will, most likely, end up being sent to Further Training due to her disabilities. She doesn't know what that entails, but she'll do her best to make sure it never happens.

Jonah is more concerned with focusing on his future and what he wants to do after the Exit Exam. Having grown up completely abled, he has no fears of Further Training.

Two different people, two different segments. The only thing that joins them is the air raid that comes from nowhere. A virus that kills many and disables the rest.

And the rest of the world is silent. What happens to segment life when the segment falls apart?
