Aeryn is living in a post-apocalyptic world. Disease spread, the world's population was diluted by half, bombs were dropped, and mutants were created from the radiation. Simon, the closest thing Aeryn has to a father, is the leader of their formed community. There is no government. Just waste lands. Aeryn is team leader of a patrol team containing three of her best friends--Julian, the boy she grew up with and the keeper of her heart; Sadie, the eccentric girl with a passion for causing trouble; and Mark, the wise boy with an old soul. They go where assigned and they wipe out mutants. It's a hard life, but some one has to live it. When Aeryn finds herself contaminated with the disease, Simon, Julian, and the rest of her team, race to find a cure. But something happens to Aeryn that changes her life forever. And she soon comes to find out just who her friends are...and who are her enemies.
Season 4 of The Virus Within
Trinity is familiar with zombies, being one herself, but when strange zombies start appearing, she realizes that the world she knew might be changing yet again.
When a dangerous set of scientific notes are discovered, Trinity and her friends don't realize anything is wrong until a frantic radio call comes in. Unaware of the notes, they race to the south and struggle to determine where the strange zombies came from. The zombies are unlike any ranks previously seen, and they aren't as predictable. Some have new tricks hidden up sleeves, forcing any Stronghold they encounter to quickly adapt to the new challenge or risk being overrun. Secrets never remain hidden, and zombie apocalypses never make life easy.
