John Porter didn’t expect his experiment to go horribly awry and send every Tommy in town on a rampage. The steam-powered metal men tore down half of Sprocketville before they were stopped. John expected a visit from the sheriff, not a robber who stole his heirloom crystal and then shot him in the chest for good measure. In a day filled with the unexpected, the biggest surprise of all was surviving to be interrogated, and then deputized, by legendary lawman, Wild Bill Hickok. Now John must accompany Wild Bill and track down his stolen crystal before his would-be murderer can use it to create the most powerful and deadly weapon ever known.
