There is a town called Wormwood.  At least, that's what it's called this time.  It has gone by other names, it has existed in other places.  But this time, it's due to appear in the American West. Every time it appears, explorers and adventure seekers go out of their way to find it and unlock the secrets of the town. The biggest secret?  In the center of town there is a doorway into heaven.

The Good, the Bad and the Infernal is the story of a few of these explorers, none of whom realize what kind of journey they are about to embark upon.  Wormwood has a way of testing people, throwing weird mystical and supernatural obstacles in the way to challenge anyone who approaches, from people-eating towns to steam powered people.

The story is told in several separate, apparently unrelated, sections, one from the perspective of a banker on his way West, another featuring a band of villainous circus performers, and a third of a British inventor, his daughter and a group of monks.  It's pretty short, but it leaves a lot open for the next in the series, least of all the arrival at Wormwood.

There is a wildly inappropriate scene near the beginning of this book, FYI, so I'll aim this firmly at the older teens, but otherwise, neat premise.
