Dead Man's Run, Volume 1 — Greg Pak

Hell is a prison from which none escape. That's not a metaphor. It's a concrete reality surrounded by razor wire and gun towers in the middle of the California desert. But today, a young cartographer named Sam Tinker begins an epic battle against the mysterious Warden and all the horrors of her domain, in a desperate attempt to rescue his sister Juniper--the only innocent in Hell!
