VAX: A post-covid dystopia

Freedom Valley is a safe place to live. Behind the wire, Brin is safe from the City, safe from the armed Guards who patrol the Fence, and safe from the Medics and their injections of the poisonous Vax. But Brin is starting to wonder if the Valley is as safe as they have been taught. Her brother, Clem, had been asking questions and has disappeared, and when Brin finds a paper with Clem's writing on it, she realises she must discover the truth to save her family before the Sickness comes again.
