From the Back of the Book:
South of the Border
You're on the run from the law. You've got enemies aplenty in the States, from undead bloodsuckers to nine-foot werewolves. Folks are coming after you with fire, silver bullets and magick. But that's all right, because you're just a few miles north of the border. And you figure once you get to Mexico, your troubles will be far behind. Bad, bad move, amigo.
And Just North of Doomsday
If you thought Mexico was immune to the troubles of the Savage West, you're all kinds of wrong. There are gangs of vampires riding the night, pulling down everyone who gets in their way. There are shapeshifters with long memories and a list of grudges, and they'd all be happy to take some of their grievances out on you. There are ancient blood-cults and twisted immortals from the time of the Olmecs. There's corruption and murder and chaos waiting for you. Good thing they celebrate the Day of the Dead down there - you'll probably be in a state to appreciate it soon enough.
