Mia is separated from her fiance when a war starts in Europe. When she finally manages to escape to America to find him and his little sister/daughter, Kellie, she finds that the last location they were in was the CG Facility, a massive worldwide organization that supposedly makes "better" humans that can't get sick. Mia arrives and finds the entire main facility abandoned.
Mia, after entering, immediately notices that something is horribly wrong here with blood and dead bodies and abandon military vehicles. She soon finds herself in a sewer on the ground level where she meets the patients of this facility. She finally learns the horrible truth of what is happening here...or what has happened. The CG Facility was making people who could rival superman and God. A lot of the tests were successful, however, all the patients became insane with only a few exceptions. One day, without any known reason, every patient escaped...and they ranged in the billions. 2.8 out of the 6.4 population in total are patients.
Mia now must try to find her friends, fiance, and Kellie through a facility of insane super-powered killers. However, she'll soon learn that not everything is so black and white. The patients, while insane, were still once human and still have morals. The survivors on the other hand are willing to do anything to just get by. Mia will have to face hard choices that will test the entire definition of morals. For example, You can kill a child who is in control over an entire infection, and doing so will get rid of the infected. However, the infected will only attack if provoked or disturbed and the child has no idea that any of this is her doing and just wants to be left alone. Or is it better to kill a bunch of semi-sane patients over a group of survivors that have done things worse than the patients have ever done?
Mia also is beginning to learn that she might not be normal herself as she gets a horrible vivid glimpse of the future that shows her dying, which she uses to avoid dying in the same horrible manner...only those glimpses may not be glimpses.
(I wrote the original one but low and behold, it got lost since I changed accounts and I currently can't get it back. I have a chapter that was in the future here so enjoy that for now!)
