With my parents' role in a massive political conspiracy exposed, I ended up on the run, desperate to rescue my little brother, Charles, from the clutches of The Opposition. I used to hate my father's obsession with disaster prepping. But as I fight my way across a war-torn country and into a secret military research facility with only my stepsister to count on, I realize that following Dr. Doomsday's Guide for Ultimate Survival might be our only hope of surviving to see Charles again. MacKenna Once, I had it all. The right backstory. The right qualifications. But my life as a student journalist was destroyed forever in the explosions that triggered the country's meltdown. Now I'm determined to help Jinx get our little brother, Charles, back. But we also have to find our own reasons to survive. Somehow, I've become the first reporter of the new civil war. In a world where your story is your ultimate weapon, I have to become the toughest freedom fighter of all.
