Stranded in the middle of the Mojave Desert, surrounded by zombies, Vivian and Axl are sure that they're facing the end. They meet a billionaire who's promised them safety and security, but it's almost too good to be true. Vivian hopes that she'll finally able to deal with the loss of Emily, her growing feelings for Axl, and the terrifying new world they're facing. But their sense of security is soon shattered when they discover that the shelter isn't the utopia they thought it would be. It seems that the company that built the shelter decided to solve their financial problems by selling off provisions, which means that the group has to find a way to get supplies-or face starvation. And Vegas is the closest city . . . With her feelings for Axl stronger than ever, Vivian volunteers to accompany him and a few others on a trip into one of the biggest tourist cities in the world. Vegas is overrun with zombies, but there are other survivors as well. As the emotional baggage piles up, Vivian and Axl's bond grows, but it doesn't take long for them to realize that zombies aren't the only thing they have to fear.
