No matter what they say, nothing ever stays in Vegas. Vanya, a sleek, lascivious, silver-tongued serial killer from Australia knows this all too well, with a lot to pay for and even more to pay back to the boys on the leash of Jaeger, the leader of a crime syndicate that specializes in human trafficking. This time, a college student named Shana is on Jaeger's menu.
But there's more to Shana than what meets the eye, particularly why Jaeger is so anxious to capture her. Even more so, a mysterious cult of ruthless Russian mercenaries has emerged, worshiping an ominous plague doctor who is not what he seems, also taking an interest in Shana.
With Jaeger's syndicate and the plague doctor cult both competing to see who will acquire Shana first, Vanya finds herself embroiled in a harrowing conflict of murderous escapades, biological warfare, and past regrets rampaging throughout the Southwest, as Vanya may be far more than just Shana's last hope.
