From the introduction:
You knew life would be rough out on the frontier, but things have gotten even worse in the lonely border town of Tumbleweed lately. The hills are full of vicious bandits, hungry coyotes, and angry natives, but also gold, which means there’s also a heap of greedy prospectors, scheming politicians, and cheating rustlers. You can feel it in the air – events are coming to a head and when the dust settles, Tumbleweed won’t be the same quiet little town it once was. You and the rest of the passengers who just arrived before the train station shut down are stuck here until the troubles pass, so you might as well team up, find out needs doing, and saddle up.
