From the back of the book:
For hucksters, poker is a way of life. It's not just a means of making a living (although it can be mighty useful that way, too). No, it's their gateway to the Hunting Grounds - a nightmare realm of arcane power - and their means of manipulating the demonic manitous that call that place home. That's the true font of their sorcerous powers.
Hucksters and Hexes is packed with all sorts of vital information to make the life of a huckster a whole lot more interesting. There's the tale of Hoyle's Book of Games - the tome that launches every cardslinger down a slippery slope toward enlightenment or damnation - plus new relics to broaden any huckster's horizons, and a whole new way to help them cast their deadly spells. Its also got rules for tempests (a new kind of huckster), tricks (a new kind of hex) and desriptions of over 100 hexes!
There's top-secret stuff for the Marshal, too, revealing the darkest secrets of the hucksters, their friends, and their foes, plus a full-scale adventure suitable for any posse.
So go ahead. Pick a card.
Just hope you don't pick wrong.
