Ugh. You would think that someone with as much historical research as Resnick has demonstrated, could come up with a better book. We have some waffle about Ned Buntline and Thomas Edison making a steampunk workshop. Wyatt Earp being assigned to protect them. Something about the native nations fighting back and winning against the USA. And of course, Doc Holliday waltzing through everything, faster and deadlier and funnier than everyone.
Resnick really, really wanted to write another OK Corral story. He found a way to publish it by draping it with cogs and bulletproof brass.
