Christian Hunt and the small band of Camp Holly survivors begin their trek west toward Hoover Dam. There, Doctor Tripp believes she and the refugees that have fortified the dam can develop a cure from Christian's blood. Zombies are an ever-present danger, opportunistic humans threaten their very lives, and scabs are evolving into apex predators, with humans on the menu. As if the near impossibility of making it past all of these obstacles wasn't enough, Christian strives to search for his family. Did his parents or sister survive? And if they did, are any of them immune like him? His desire to find out what happened to them puts the entire mission in jeopardy. And what he discovers is that knowing is sometimes worse than not knowing. With new friends, enemies, and dreadful discoveries, the companions will have to pull all stops and endure more pain and hardship than ever before. Christian learns to love, hate, kill, and nurture, all while trying to hold on to some semblance of humanity. Is the road too dark and perilous for the fellowship to travel? Does Christian find his family? What new horrors will be revealed by the ever evolving Monostrovis Virus? To find answers to these questions and more, join Christian, Fish, Boomer and the rest of the motley crew on their Crusade!
