Thalia is a 17 year old girl trying to survive in a post-apocolyptic world. Despite a constant threat of clickers, stalkers, and tendrils infiltrating her body, the real threat to humanity is themselves. After spending 15 and a half years of her life in the Denver QZ, Thalia has a burning passion to see the world. Her and a group of kids escape the QZ, opening themselves up to a world of hurt, yet also a whole new world. Thalia runs into Joel and Ellie along her way. Ellie and Thalia numb each other's pain in a way no one else could.
