In Edin, when you turn eighteen, you have to do national service. Six-months outside the city's walls, fighting the diseased hordes. Only half the recruits survive. Spike refuses to be just another statistic. Beyond These Walls is a post-apocalyptic epic. Join Spike, Matilda, and their friends as they leave their city for the first time to face the brutal reality of national service. Some of them won't return, and for those who do, their lives will never be the same again.
