My name's Bryn Mathis. I'm seventeen years old, and I'm alive at a critical time in our world's history, unlike all the adults and babies who didn't survive the virus that almost wiped out the human race. Alliances are building, enemies are gathering, and everything's about to reach the boiling point. I'm in a race against time to get Haven ready for the final showdown, a confrontation that could very possibly destroy everything my friends and I have worked so hard to create. People I trusted have betrayed me. People who I thought were my enemies are not. Nothing is as it seems, and nothing will ever be the same for me, now that I've embarked on this one last adventure that could be the undoing of everything that is me. Contains violence and some foul language.
